4. Last Minute Risk Analysis (LMRA)

Safety begins with you. No matter how well prepared you are, situations may occur in which you are confronted with dangers you failed to consider during preparation. Sometimes these dangers are only visible in the workplace or near vicinity. Therefore, we call upon your knowledge, experience and expertise: perform a Last Minute Risk Analysis.

Stop before you begin! Analyse the risk!

1. What do you think can go wrong and what dangers do you see? Think about it!

2. What are the causes? Take action!3. What will you do to prevent danger? Ask for help if you need it!4. In case of doubt, do not start. Consult your manager.

Everything OK? Check!

1. Personal protection measures present: helmet, glasses, hearing protection, safety shoes, gloves, etcetera.

2. Safe escape route known and accessible?3. Work licence OK? Consulted manager? Procedure OK?4. Personally checked whether installation has been properly

secured?5. Are the correct tools being used?6. Unsafe situation? Stop work and warn colleagues.7. Environment sufficiently shielded against sparks and flame?8. Everything safe and in order for working at height?9. Respect traffic rules and safe walkways! 10. Workplace tidied up?

• In case of alarm, follow instructions. Go to the collection point closest to your workplace;

• Unsafe situations and actions, incidents, accidents and near-accidents must be reported to your direct manager immediately;

• Always have injuries treated, no matter how small;• If mobile telephone use is not permitted, this is indicated

by signs. Mobile telephone calls by drivers are only permitted if a car kit is used. Mobile phone calls should be kept to a minimum.

You must ensure good PPE maintenance yourself. Pictograms at the gate or installations also indicate which PPE must be used.

An overview of the PPE and the requirements they must meet is presented below.

7. Incidents and dangerous situations

• OSHA definitions are used for incidents. If you identify a dangerous situations, action, undesired event or incident, you must report it to your manager as quickly as possible. Dangerous situations include situations that may result in injury, material or environmental damage. (Procedure P024);

• If the danger is acute, you must immediately call the emergency number (last page of this booklet) and report the danger to the watch and your manager. Every incident must subsequently be reported via the HS&S reporting point. Ask your manager about this and fill it out with or without your manager;

• If you are confronted with high-risk activities, talk to the person in question in order to correct the unsafe activity and continue the work safely. If necessary, report this in HS&S reporting point;

• Do the following in case of an incident: - Immediately call the emergency number (see back of

booklet for numbers); - Alert the watch and expert help yourself or via your

manager; - Ensure the situation is safe again as quickly as possible.• Should an undesirable situation present itself, also ensure it

becomes safe again as quickly as possible. Then warn your manager. Subsequently file a report (together) in the HS&S reporting point, after which the manager may initiate and investigation;

• Resolve the situation if possible (always consider your own safety and that of your colleagues).

16 17

In the event of fire, explosions, a serious incident or serious environmental threats, an evacuation alert may be given via sirens or spoken word.

• Stop your work safely: turn off machines and close gas tank valves. Work orders are always invalid during an alert;

• Immediately evacuate the building or workplace via the shortest route;

• Do not use elevators;• Telephone use should be kept to a minimum;• Immediately go to the nearest assembly point;• Follow all emergency personnel instructions;• The end of an alert is announced via a brief siren with

spoken text.

8. Hygiene and environmental rules 8.1 Order and neatnessIn order to prevent contamination (hygiene), discomfort for others and an increased risk of fire and incidents, everyone must work in an orderly and neat fashion. This means, among other things, that each worker is responsible for keeping his own working environment clean while performing his work and for leaving behind a clean and neat workplace at the end of the (day's) work. 8.2 Chemical waste Employees and contractors must ensure that waste released during work is immediately disposed of in the appropriate waste containers from the workplace. Waste that may attract pests must be deposited in the appropriate sealable container. Small chemical waste must be handled and disposed of separately. If you have waste and are unsure of its type, contact your manager. 8.3 Dangerous substancesDangerous substances must be stored in accordance with PGS 15, 'Storage of packaged dangerous substances; Fire, occupational and environmental safety guideline'. Dangerous substances may not be brought onto the Essent site without permission. (Procedure P023)

18 19

8.4 Air/water/ground emissionsPossible (incidental) air/water/ground emissions must be reported to the local Business Support department (or project management) in advance. An emission must also be reported if it has already occurred. The department will determine whether it is permissible, and up to what level. 8.5 Noise Possible (incidental) noise emissions must be reported to the local Business Support department (or project management) in advance. The department will determine whether it is permissible, and up to what level.

8.6 Traffic movements When planning additional traffic movements, management or the license issuer must evaluate the route that needs to be taken in order to minimize nuisance and/or damage to roads. This includes things like mobile cranes that block roads by blocking the through walkway and/or escape routes. 8.7 Setting up temporary installationsRequired temporary installations must be reported in advance. In consultation with management, a suitable location for the installation will be assigned. Temporary installations must meet legal requirements and standards.

8.8 Setting up temporary buildings Required temporary buildings must be reported in advance. In consultation with management, a suitable location for the building will be assigned. Temporary buildings must meet legal requirements and standards. 8.9 Waste Different types of waste are found at workplaces, construction sites and overhaul lots. You must ensure your contribution to this waste is as small as possible. Additionally, you are required to clear waste correctly, i.e. separated by type where possible. Deposit the waste in the designated containers. If the containers are not present, contact your manager. (Procedure P018) We distinguish the following types of waste:• Household (household waste, cardboard and paper waste,

mixed with plastic, plastic cups, etc.), commercial waste (wood, insulating materials);

• Metal waste (stainless and carbon steel waste, electrodes, welding wire, drill shavings, etc.);

• Paper waste (paper and cardboard waste without plastic coating). Note: sanitary paper products are not part of this waste type;

• Small chemical waste. It goes without saying that small chemical waste requires particularly careful handling.

20 21

The following waste products must be sorted separately into the designated containers:• Paint waste, such as paint cans, brushes and stirrers;• Oil-containing waste, such as absorbents, cleaning cloths and

gloves; • Empty packaging, such as caulk tubes, turpentine and paint

thinner tanks, cans and spray cans;• Small chemical office waste, such as Tipp-ex, felt-tipped

pens, toner and printer waste;• Fluorescent lights and other energy-saving bulbs;• Processed oil;• Batteries.

If you have waste and are unsure of its type, contact your manager.

9. Visitors

22 23

10. Contined Spaces There are specific risks associated with working in enclosed spaces. For example, working in storage tanks, tanker trucks, reaction kettles, narrow open casks, cracks, elevator shafts, wells, sewers and pipelines. (Procedure P001)

Real dangers are: • Risk of fire and explosion;• Risk of suffocation and intoxication;• Injury caused by moving parts;• Electrocution;• Injury due to falling, slipping and falling objects. You must therefore always take the necessary precautions:• First check the work order and additional licenses;• A sign with the text 'Enclosed space' must be present at each

access point;• Check whether working conditions are safe (this must be

indicated on the work order), for example by conducting a gas or oxygen test or a test for the presence of dangerous substances;

• Never work alone, always ensure direct supervision via access through a safety/hatch watch and ensure you can communicate clearly with the safety/hatch watch;

• The safety/hatch watch always remains outside the enclosed space and will sound the alarm if danger is present;

• Always ensure good lighting and ventilation;

• Only safe currents are permitted when working in an enclosed space, a maximum of 50 volts AC or 110 volts DC, or air-powered tooling. Inverters and safety transformers may not be placed in the enclosed space;

• Limit your stay in the enclosed spaces;• Make plans for the evacuation of possible victims inside the

enclosed spaces.

24 25

11. Working at height

Working at height always entails a risk of falling. (Procedure P111)

11.1 Fall prevention• Fall prevention measures must be worn at insufficiently

secured places higher than 2.5 meters. The catch line may not be longer than 1.5 meters. If fall prevention equipment has been loaded, it must be re-certified or replaced;

• Suitable measures are required when working on rooftops, such as the use of railings or roof edge security;

• Suitable hard screens must also be placed near wall and floor openings where a risk of falling exists. Suitable is understood to mean a screen of sufficient strength and at least 1 meter high, with kneeling edges and a skirt, if necessary. Openings, such as stairwells and openings, must be closed off using sufficiently strong material or with a screen.

11.2 Scaffolding• Only access certified scaffolding. This scaffolding is labelled

with a green 'scafftag' in the label holder. This certification is valid for 1 month. Examine the scaffolding and determine whether it is safe yourself;

• Scaffolds may only be accessed via the ladder, not via the construction;

• Always keep the scaffold you are working on clean. Immediately remove any unnecessary materials and waste. Consider the people walking underneath the scaffold;

• Only a licensed scaffolder may build, modify or remove scaffolds. In such cases, the scaffold is marked 'scaffold not ready'. Removal or changing scaffolds by unauthorized individuals may result in sanctions. A scaffold must be certified by a scaffolding inspector;

• Special scaffolds must be certified by an independent third party;

• Incidents in which forces have acted on the scaffold that may endanger safety (such as storms or freezing) require renewed inspection before the scaffold may be accessed again;

• Application of tarps, screens and similar is only permitted after consulting the scaffolder. The procedure for special scaffolds then applies;

• Immediately vacate the scaffold in case of storm (lightning). Report unsafe scaffolds to the scaffolder, scaffolding coordinator or manager.

Checkpoints for scaffolds:• Do not use wooden (scaffold) components if temperatures

are elevated;• Are floors, ladders, steps and escape routes clear of

scaffolding material and obstacles?;• Are there no projection parts at walking height?;• If the scaffold is used as a hoist, it must be built and certified

to this end. The maximum load to be hoisted must be indicated on the scafftag;

26 27

• Are spindles placed on a level surface and fully seated on the boots, ensuring the scaffold is efficiently supported and protected from sagging?;

• Are all beams and supports present?;• Is the work floor laid tightly and are the planks undamaged?;• Are floor planks sufficiently secured against springing, wind

and shifting?;• Are side planks fitted around the entire work floor, properly

affixed and tightly fitted to the floor?;• If the work floor is 6 meters or higher, a security floor is

mandatory;• Are railings and knee rails positioned 100 cm and 50 cm

above the work floor, respectively?;• Does the ladder extend at least 1 meter above the stepping

off point, and ensure the ladder is attached at a minimum of three points;

• The stair entry of a work floor must be protected by a safety bar or gate;

• Is a stair rail present for ladders higher than 6 meters?;• If you use electric tools on the scaffold with current that

exceeds safety current, you must always use a ground switch (30 mA);

• The scaffold must be grounded.

11.3 Rolling scaffolds The following safety rules apply to rolling scaffolds: • Rolling scaffolds must also be certified and labelled (scafftag);• Consult the assembly manual and manufacturer instructions

before constructing or using the scaffold;• A rolling scaffold must be assembled upright, not on its side;• Check whether various components are in good condition

before using the scaffold;• The maximum standing height for indoor work is 12 meters;• The maximum standing height for outdoor work is 8 meters;• You can widen the base using triangle or roll stabilizers;• Ensure the rolling scaffold is situated on a sturdy surface;• The work floor must always be fitted with skirts;• Ensure all of the rolling scaffold's wheels are blocked during use;• Do not use steps, ladders, etc. on the rolling scaffold work floor; • Hosting equipment may not be affixed to the rolling scaffold;• Do not use a rolling scaffold in the vicinity of sections that are

under current;• You may only climb the inside of the rolling scaffold;• Nobody may be present on the rolling scaffold while moving it;• Push or pull as close to the base as possible when moving the

rolling scaffold;• Ensure a rolling scaffold is properly secured when it is left

outside unattended.

28 29

11.4 Ladders Ladders are designed to bridge a height (climb) of up to 7.5 meters. If work must be performed on a ladder, first determine whether it is legally allowed. The decision tree can be used for this, see Procedure P111 working at height. Follow the instructions below:• Check whether the ladder is in good working order;• Check whether it is labelled with a certification sticker and an

inspection date less than a year old;• The bottom of the ladder must be fitted with non-slip feet or

a stabilizer bar;• Only place the ladder on and even, firm surface and never

place extensions;• Ensure the ladder extends at least 1 meter above the

access site;• Never place the ladder in front of a door or in the vicinity

of electrified sections;• Affix a warning tape or safety cones where necessary;• Fasten the top of the ladder if possible;• Place the ladder at a 65° to 75° angle;• Never extend the height of the ladder by placing a box,

container or other objects under it;• Never use a ladder as a walking plank;• If you are working at a height of over 2.5 meters, always wear

a safety belt and hook in if possible.

12. Working near water Assume that an accident at a quay or dock involving a fall is usually more serious due to wet clothes; swimming in work clothing is almost impossible. Water that is too cold results in hypothermia and can lead to death within 10 minutes. Additionally, you can inhale water, which can cause infections (Weil's disease).

To reduce drowning risk: • Use an approved life preserver and remember to take

additional weight into account (tool belt);• Use fall protection measures;• Keep the working environment clean (risk of tripping);• Ensure supervision during work activities;• Ensure the presence of rescue equipment (boathook and

lifebuoy);• Avoid slippery surfaces (oil, snow, ice).

• Only use double-shielded electrical hand tools, recognizable based on the symbol;

• Secure equipment before a repair or adjustment is carried out;• If equipment is not being used, the plug should be removed

from the electrical socket;• Cable reels must be extended fully during use to prevent

overheating;• Never place cables and wires in the walkway and use S hooks;• Work in a dry environment: if there is a risk of water entering

the reel, place it upside down;• Protect electrical sockets from filings and dust;• Do not use damaged tools and cable reels - present them for

repair and certification;• Electrical equipment may only be connected to permanently

mounted, mobile, grounded sockets or operated using safe current (below 50 volts AC or 120 volts DC).

13.4 Hoisting equipment There are clear rules for working with hoisting equipment. Hoisting equipment includes:• Slings of steel, rope, plastic, et cetera;• Hoisting bands;• Chain and steel cable hoists;• Chains;• Steel cables and jacks.

13. Tools and equipment

13.1 Certification (Hand) tools and equipment, such as fire extinguishers, electrical tools, ladders, hoisting equipment and so forth are periodically checked to verify they still meet set requirements. (Procedure P022)

All certified and/or checked tools and equipment may be recognized by a certification sticker and a unique number applied in or to the tool. The sticker indicates when certification lapses. Check the expiration date prior to use. Check for external damage, wear and items such as oil levels.

13.2 Hand tools and equipment (Hand) tools are an aid for performing the work:• Use the tool or equipment for the intended purpose; • Check whether the tool or equipment is in good condition;• Replace materials as required. If this is impossible, the items

must be labelled and taken out of service;• Have professionals perform repairs.

13.3 Electrical equipmentElectrical equipment (both portable and stationary) must be certified annually in accordance with NEN 3140 and NEN-EN 50110. This is visible on the certification sticker. • Check for the presence of a certification sticker and expiration

date, this also applies to rented material;• Safeties may not be bridged or removed;

32 33

16. Dangerous substances 16.1 GeneralA dangerous substance is any substance of which small amounts may cause damage to people or the environment as soon as it ends up outside its packaging. Dangerous substances may be explosive, flammable, toxic, corrosive, contagious, irritants, caustic or radioactive and form a danger to the environment. Various substances have multiple dangerous properties combined.

Dangerous substances may be recognized by the label. In addition to the information on the label, more extensive information is available on the product information card or material safety data sheet for the substance in question.

Ask your manager which precautions and personal protection measures you need to employ prior to working with the substance. 16.2 Asbestos fibres, ceramic fibres and slag wool Released asbestos fibres can cause severe health damage. Therefore, it is important to inform the DTA employee on site in the event asbestos is identified. Work must be suspended after inspection/on indication. The site where asbestos was found must be cordoned off with the appropriate tape (which states: 'do not enter - Asbestos processing'). Follow the DTA employee's instructions. Only certified companies may remove asbestos andsimilar materials.

44 45

Work that may involve the release of ceramic and slag wool fibres must be treated in the same manner as asbestos. (Procedure P015) 16.3 Fly ash and coal dust Fly ash is a by-product of coal combustion. Inhalation of fly ash may be harmful to health. Wearing good respiratory protection is necessary when working in an environment where fly ash or coal dust may be released or is present.

Danger symbols according to the GHSIn Europe, a clear system for identifying the risks associated with dangerous substances has been selected; the GHS (Globally Harmonized System). An overview of the symbols used is presented below.

16.4 H and P statements within the context of the GHSIn addition to the danger symbols, danger may be evaluated based on the H&P statements. H (Hazard) indicates the hazard and P (Precaution) indicates the precautionary measure. The statements are followed by a number. Next is a description of the hazard and the precautionary measure. H&P statements must be affixed to the user label on the packaging. A few examples:

Examples of hazard statements H: • H271: may cause fire or explosion, strong oxidant; • H318: causes serious eye injury; • H410: highly toxic for waterborne living organisms,

with long-term effects. Examples of precautionary measures P:• P102: keep outside of reach of children;• P211: do not spray into open flame or other incendiary

sources; • P336: thaw frozen body parts with lukewarm water,

do not rub.

You can find a listing of the H&P statements in the Chemical cards book or on the Chemiezone site www.chemiezone.nl (only for Essent employees). Where applicable, H&P sentences must be stated on the product information sheet of the relevant substance in each case.

16.5 Contamination with a dangerous substance If you come into contact with dangerous substances, do the following: • Look on the production information to see what to do;• Remove contaminated clothing as quickly as possible;• Avoid contact with the contaminant;• Rinse the skin under running water for 10-20 minutes;• Warn your manager;• Contact the first aid staff or occupational physician.

17. Explosion risk (ATEX) The Atex (French: Atmosphère Explosive) encompasses responsibilities for risk inventory and drafting explosion safety documents for preventing explosions. It is Essent's duty to promote safe work.

In turn, the employee is required to act safely. Special rules apply within an explosion risk (Ex) zone. In order to perform work in an Ex zone, a work order is mandatory. The work order outlines the special rules and regulations that apply to the Ex zone. The location may be recognized by the Ex sign.

The golden rule within the Ex zone: Do not cause sparks or use open flame!

18. Fire prevention 18.1 General Every employee is responsible for good fire prevention. Know how fire and explosions may be prevented, and where fire extinguishing equipment and manual fire alarms are located. 18.2 Open flame prohibited Fires may develop in a number of ways in the workplace, on the worksite and the construction site. Pay special attention to: • Leaking oxygen hoses;• Leaking gas hoses;• Sparks from cutters;• Welding filings;• Flammable substances;• Static electricity.

Be careful when welding. Always use a welding blanket to cover and/or protect grate floors or areas with a high fire risk.

Smoking is only permitted at indicated sites. Smoking is not permitted at other locations. Never throw a smouldering cigarette into the garbage.

A fire extinguisher suitable for work must always be present.

If a fire marshal is required, this is indicated on the work order. (Procedure P001)

Limit the day supply of dangerous substances to the day supply. Other substances remain at the storage site.

18.3 FirefightingYou may occasionally need to perform work involving a risk of fire. Always ensure a certified, suitable fire extinguisher is nearby. If necessary, keep floors wet (for example for coal dust).

Everyone is required to combat fire initially. Also adhere to the following rules: • Your own safety is paramount;• Stay calm;• Turn off gas and electricity as quickly as possible;• Have someone call the emergency number;• Clear the workplace; • Start putting out the fire;• Follow fire department and emergency service instructions.
