These protect against risks or irre-versible injuries and fatal exposure. The design is more complicated. They are certificated by an appro-ved laboratory and quality control

certified by the same organisation. E:g, Safety helmets, fall arrest systems, chemical resistant gloves, etc.

Designed for medium level risks. These protect from everyday risks in industry. Certificated by an acre-dited laboratory or controlled orga-nisation (HSE). Eg, safety footwear, safety goggles, ear defenders, etc.

Simple in design. Protects against minor risks. These types of PPE are self-certified by the distributors or manufacturers. Eg, non technical work wear, gloves for low risk activi-ties, etc.

APPLICABLE LEGISLATION

Directive 89/656/CEE. The sale and free circulation of policy guidelines regarding personal protective equipment (PPE) within the comunity.

RESPIRATORY PROTECTION


Masks are available with filters that can be replaced when they become less efficient. These cartridges should always comply with regulations EN 141 and 143. They contain activated charcoal that purifies the air which is

inhaled when you breath the fumes of solvents or dust. It is a good idea to use these masks when cleaning spray guns and painting equipment with solvents and when certain paint products are sprayed.

EN-149: Disposable filter masks (5). Prevents the inhalation of air contamina-ted with dust and/or water based aerosols when sanding putties and paints. They filter out particles up to 5 microns and are classified as FFP1; FFP2 and FFP3. They do not protect against solvent vapours.

EN-371: Type AX filters. For vapours and mixed filters.

EN-405: Masks with valves for improved efficiency. These masks protect against gases and vapours. They have fixed filters which cannot be remo-ved. They should be dispose of when their efficiency reduces (6).




TLV (Threshold Limit Value): This is the maximum concentration in the air of a substance that you can be exposed to, calculated on a for 40 hours a week basis, without risk to your health.

Nominal factor of protection: The ratio between the concentra-tion of a chemical in the air and the concentration inside the mask. It is calculated using tables within the EN regulations.

To choose the correct filter it is important to know the contaminant, its concen-tration and its toxicity. The maximum exposure level, the nominal protection factor of the equipment, and the factor of protection are also required.

OTHER LEGISLATION RELATED TO THE SUBJECT:

EN-1146: Respiratory protective devices Self-contained open-circuit compressed air breathing apparatus (7). Motorised equipment filters the air and pumps it up to the mask or an approved hood. This provides clean air inside the mask protec-ting the worker. The correct type of filter should be chosen for the type of work, ie, gases, particles or a combination of both.

EN-401: Self contained closed circuit breathing apparatus (8). Equipment that ensures a clean supply of air from a cylinder to a face mask. It maintains a positive pressure inside the mask protecting the worker.

As well as providing clean air to brea-the the face visor should be supplied with clean air from a charcoal filter. The air contained between the face of the operative and the screen is held to

a higher pressure than the one in the outside to prevent the contaminated air from entering the mask and being breathed by the operative.

The protection factor is the relationship between the average concentration of the chemical in the workplace and the threshold limit value (TLV).

The protection factor required is calculated dividing the average concentration of the contaminant by the TLV. The correct equipment should assure a nominal protection factor higher than the required. For example:

Contaminant: Xylene

Concentration: 4,340 mg/m3

TLV: 434 mg/m3

Protection factor required: 4,340 / 434 = 10

4,340/434=10 (nominal factor protection > 10)

Changing the filters: It is impossible to know how long a filter will last for. This is because there are many factors that influence its life, eg, relative humidity, tempe-rature, respiratory rhythm, lung capacity, concentration and type of the contami-nant. The filter should be changed when it becomes more difficult to breath or the smell of the contaminant is noticed.

NOMINAL PROTECTION FACTOR

Ambient contaminant concentration / Concentration inside the mask/respirator

Antistatic shoes or boots must be worn in workplaces where flam-mable materials are used or static electricity needs to be minimised. These shoes should have conductive soles, which are designed to reduce

the accumulation of static electricity, but they must still maintain an elec-trical resistance of between 105 – 109 ohms. These shoes must not be worn near open electrical equipment or high voltage equipment.

Safety footwear must have antislippery soles, resistant to abrasion, oils, hydro-carbon, and heat. If there is a special risk on impacts, punctures, electric shocks or static electricity, suitable footwear must be used.

Depending on risks, the safety footwear should offer additional protection. Safety footwear must be used where there are anti-slip floors, a risk of burns,oils, heat or hydrocar-bons. If there is a risk from impact, punctures,electric shock or injury, safety shoes must be used.

When working with paints and sol-vents safety footwear should always

be worn. This footwear should be antistatic and resistant to chemicals.

Solvents and thinners dry and damage the skin. Pathegenic germs can also sensitise the skin causing conditions

that show up years later. For this reason certified gloves must be used.

Gloves to protect against chemicals and microorganisms. The Terminology and requirements are explained in this regulation.

For Gloves to protect properly against chemicals and microorganisms it is necessary to measure their resistance to chemicals. Gloves are tested by taking a random sample from a batch of gloves and checking them for holes. This is done by filling the gloves with air or water to see if they leak.The number of defective gloves per batch is called the AQL or Acceptable Quality Level. A high AQL number shows a low quality batch of gloves.There a 3 levels:

Gloves are tested this way to check their effectiveness against liquids and microorganisms. To be certified as anti microorganisms, at least level 2 or AQL of 1,5 is compulsory. Level 1 gloves should show a pictogram proving their suitability for the use under general chemical risks. Gloves with level 2 should have pictograms both for chemical risks and for risks due to microorganisms.

A plan must be set up to change the gloves periodically and to make sure that they are changed before they become less effective against chemical products.

Using contaminated gloves may be extremely dangerous due to the accumulation of contaminants in the fabric of the glove.

Gloves should always be cleaned following the manufacturer´s instructions.

Safety goggles are used to protect the eyes from chemicals and flying particles. Goggles should be worn when handling solvents.They should also be worn when using compressed air blow guns to remove dust and to dry solvents after degreasing.

Prescription safety goggles are available for people who regularly wear glasses.

People that need to wear contact lenses during painting and degreasing work should be particularly aware of the following possible dangers:

It is almost impossible to remove contact lenses from the eyes after accidentally splashing a chemical substance into them.

The contact lenses will interfere with the emergency cleaning process.

Fumes and solid particles may collect behind the contact lenses in the eyes.

Following a chemical incident and the person becomes unconscious, the first aid personnel may not realise that contact lenses are being worn and that contamina-tion behind the lenses may have happened.

For all these reasons, the use of contact lenses should be considered carefully and avoided where possible.

OVERALLS WITH HOODS

These are protective overalls made of a special material called “tyvek” and they are lint free.

These overalls are very hygienic, if they are kept in their packaging when not in use. They are excellent for painting with spray guns and protecting the body from the spray paint.

People working in installations that transfer flammable liquids should avoid synthetic garments to prevent problems with static electricity. Cotton clothing and underwear should be worn. It is also advisable to limit the use of woollen clothing.

Showers and emergency eye wash stations provide instant decontamina-tion by using a lot of water to dissolve and remove a chemical product. If the chemical is not removed quickly, it could cause serious and permanent injury. Showers are the best and most practical form of emergency deconta-mination available to date.

The shower should ensure enough flowrate to allow the body to be soaked immediately. The water should be clean and between 20ºC and 35ºC to

avoid a cold water shock, and save from an insufficient exposure under the water flow that could cause an insufficient removal from the chemical contamination. Highly recommenda-ble is a drain to remove the dirty water.

The best showers are operated by a triangular handle hanging from a chain, which operates the water. Clothes, jewellery and shoes must be removed whilst under the shower to save time. This reduces the exposure time.

Contact lenses must be removed as soon as possible to wash the eyes and completely remove any dangerous chemical substances.

The water must not be applied directly to the eyeball, but instead upwards from the base of the nose. This makes the washing of the eyes more effective when removing the chemical subs-tances. Avoid powerful jets of water as they may force particles into the eye.

The eyelids must be held open to en-sure enough cleaning behind them.

It is important to ensure enough washing from the nose to the ears. This will avoid chemical substances entering the unaffected eye.

The eyes and eyelids must be washed for a minimum of 15 minutes.

After washing, it is recommended that the eyes are covered with a clean and sterile gauze. Seek professional advice immediately after washing.
