Physical Manifestations of Chemicals

25

Manifestation Description Routes of

Entry

Vapors The gaseous form of substances that are normally solid or liquid room temperature. The vapor can be changed back to the solid or liquid state either by increasing or decreasing the temperature alone.

Inhalation

Gases Some gases are: easy to detect, some are odorless and colorless, some even deaden your sense of smell.

Solids A solid is a material which retains its form, such as a stone.

Dusts Dusts are tiny solid particles. Larger particles are trapped in the mucous and hairs of the nose and windpipe. Smaller dust particles can be breathed deeply into the lungs.

Liquids A liquid is a state of matter which flows and can change its shape and is not easily compressible and maintains a relatively fixed volume.

Fumes Fumes are formed when a solid, especially metals are heated to very high temperatures and become vaporized. Example: welding fumes.

Absorption

Page 26: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

How Chemicals Enter The Body

26

You can breathe toxic dusts, gases, or fumes. These can harm your respiratory system or pass from your lungs into your bloodstream and harm another part of your body.

INHALATION

Toxic substances can get into your body if you eat or smoke without washing contaminated hands.

INGESTION

Toxic liquids can cause damage if they come into contact with your skin or eyes. Some toxic liquids can pass through your skin and enter the bloodstream and cause harm to another part of the body.

SKIN

Toxic substances can get into your body if you are stuck with a contaminated sharp object

59

This is also true for odorless substances

A solvent’s volatility and evaporation rate determines

how quickly it will evaporate.

ACUTE HEALTH EFFECTS

• Central nervous system

effects

• Dizziness

• Light-headedness

• Depression

• Nausea

• Headache

• Respiratory irritation

Evaporation of chemicals release vapors

Vapors enter the lungs

They are carried to organs of the body

Page 60: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Skin Contact with Solvents

60

Direct contact may cause drying and

chapping of skin

Solvents may pass through the skin to the bloodstream

Broken, chapped or dry skin allow

easier passage into the bloodstream

Chronic exposure may lead to

dermatitis

ACUTE HEALTH EFFECTS

• Drying of skin

CHRONIC HEALTH EFFECTS

• Red, inflamed, thick, dry skin

• Allergic skin reactions

Page 61: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Ingestion of Solvents

61

An indirect means of ingestion is more likely:

Unwashed hands

Eating or drinking in the workplace where chemicals are being used

Mists or droplets can contaminate food

ACUTE HEALTH EFFECTS

• Abdominal cramps

• Nausea

• Diarrhea

• Ingestion can cause irritation

of the gastro-intestinal tract

Deliberate and direct ingestion of chemicals is unlikely in workplace

Page 62: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Acute Health Effects

Individual SDS must be consulted for specific Health information

Chronic Health Effects

65

CLEANERS OR

DETERGENTS

• Used to remove soil, dirt, dust, and organic matter;

• They work by removing dirt through wiping, scrubbing or mopping;

• Rinsing is an important part of the cleaning process

• Used to reduce germs from surfaces but not necessarily eliminate them;

• Reduce germs from surfaces to levels that are considered safe

SANITIZERS

• Chemical products that destroy or inactivate germs and prevent them from growing;

• They have no effect on dirt, soil or dust;

• Regulated by EPA;

• Used after cleaning for surfaces with visible blood or drainage from infected skin

DISINFECTANTS

Page 66: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Sanitizers and Disinfectants

Designed to kill “pests” such as:

• Infectious germs,

• Microorganisms (viruses, bacteria and fungi)

They contain chemicals that are “pesticides”

• Exposure to persistent toxic chemicals can cause health problems

66

Page 67: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

COMMON

DISINFECTANTS

HEALTH EFFECTS

Phenol compounds or carbolic acid

• Skin – severe burns, rashes, swelling; poisoning • Inhalation - light sensitivity and sinus congestion • Ingestion may cause vomiting, paralysis, convulsions

Sodium Hypochlorite – chlorine bleach

• Respiratory irritant; can trigger asthma attacks • Skin and eye burns • Creates a deadly gas if mixed with other cleaners, e.g. ammonia

Quaternary ammonia compounds - QUATS

• Irritating to eyes and skin • When properly diluted they are non-staining and non-corrosive to most

surfaces • Products using 1% as active ingredient are toxic to aquatic life

Isopropyl alcohol • Must be 60 – 90% concentration to kill germs • Flammable • Eye irritant • Moderately toxic to humans by skin contact

Pine Oil As a disinfectant it is weak and a 70% solution is needed to kill germs

Hydrogen Peroxide (not in the form sold in drug stores as an antiseptic)

• Irritating to eyes and skin • A sanitizer in cleaning products that contain detergents is effective for

cleaning soiled surfaces

67

Page 68: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Surfaces to Clean

68

Cleaning surfaces people frequently touch is important in preventing the

spread of disease

• If sanitizing is not required, use a

cleaner

• If sanitizing or disinfecting, use a

product that is effective for the

microorganisms being targeted.

• Follow product mixing instructions

and make only as much as you

need.

• Leave the disinfectant in place long

enough for it to do its job

• Wear gloves and goggles

Components of Paints

• The thinner or solvent allows the moisture to be spread.

• It may be water, vegetable oil or solvent. Solvents may contain naphtha, ether, xylene, mineral spirits or alcohol.

Binders hold the paint’s pigment together in a film.

Binders may contain hazardous materials such as alkyd and epoxy resins.

Pigments give paint its color.

They are either synthetic dyes or metal compounds (metallic salts).

Fungicides & stabilizers control flow, suspension, bubble formation, resistance to insects/mold, temperatures, & extend service life

Acidic and basic are two extremes that describe chemicals.

The pH scale measures how acidic or basic a substance is.

A substance that is neither acidic nor basic is neutral.

When chemicals are mixed with water, the mixture can become either acidic or basic.

MERCURY

77

Page 78: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

What is Mercury (Hg)?

It breaks into small droplets that can lodge

in cracks and crevices

At room temperature, it evaporates easily,

giving off invisible, odorless and toxic

vapors

Mercury does not degrade and cannot be

destroyed.

New York State banned the purchase or

use of elemental mercury in primary and

secondary schools in September 4, 2004.

Mercury is a silvery, liquid metal that occurs naturally in the earth’s surface.

Names: elemental mercury,

metallic mercury, quick silver

Population Most Sensitive to Mercury

Pregnant women

Hg can pass from a mother’s body to her developing fetus.

Infants

Hg can be passed to nursing infants through breast milk.

Young Children

They tend to play on floors where mercury may have been spilled

They are more likely to breathe more vapors than an adult because they breathe faster and have smaller lungs.

83

High-dose fetal exposures:

• low birth weight • small head circumference • mental retardation, cerebral

palsy • deafness • blindness • seizures

Bedbug Facts

90

Bedbugs are attracted to humans through heat

and CO2

They are neither a function of poor personal

hygiene nor unsanitary conditions

The often hide in cracks in furniture, floors or

walls

They do not live on humans, but commute to

their host from a hiding place to feed

They are most active at night when people are

sleeping

They do not jump, fly or hop; they walk

They can live for several months without food or

water

They can feed on pets but do not thrive on them

Page 91: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Methods of Bed Bug Introduction

Passive

They are introduced from

another infested location, but

not by its own movement

• Furniture

• Mattress

• Guests

• Employees & Students

• Public Transportation

Active

Bedbugs migrate by walking

from an infested area

• From one room to another

• From one apartment to another via pipes, telephone or cable wires

• Down a hallway after dropping off an item being discarded

91

Page 92: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Bed Bug Infestation

They are found in

dwellings with a high

resident turnover rate:

• Apartment buildings • Hotels • Shelters • Dormitories • Nursing homes

They are also found in

other areas:

• Schools • Child care facilities • Movie theaters • Airplanes • Clothing stores

92

Bedbugs are more common:

• in the homes of people who

travel (business travelers)

• stay in hotels

Impact of Having Bed bugs

93

Bed bugs do not carry diseases

Bites on skin can result in allergic

reactions and secondary infections

Infestation can cause: • stress

• anxiety and sleeplessness,

• discomfort of bites

• social stigma

ONE LIVE BEDBUG IS

NOT AN INFESTATION

Hand-Washing Facts

108

A 2013 undercover

study found only

5 % of people wash their

hands correctly

Sanitizers can

be less effective

because people may

not use enough or may

wipe it off before it has

dried

Using

soap and water to wash hands is more

effective than water alone

because the surfactants in

soap lift soil and microbes

from the skin

7 % of women and

15 % of men do not wash their

hands at all after

using the restroom

CDC states that

failing to wash

hands correctly

contributes to nearly

50 %

of all foodborne

illness outbreaks

At least a 70%

Alcohol-based

hand sanitizer is the

best alternative when

soap and water are

not available

Hand washing

reminder signs

increase frequency and length

of hand-washing

Triclosan, an ingredient

found in antibacterial soaps, is

under review by the FDA due to

potential health concerns and

questionable benefits. A final

decision is expected by

September 2016

Women: • wash their hands

significantly more often,

• use soap more often, and

• wash longer than men.

Researchers in London

estimate that if everyone

routinely washed their

hands,

a million deaths a year could be

prevented.

Soap & water are

more effective than hand sanitizers at

removing certain kinds of

Infected blacklegged ticks can spread Lyme Disease

West Nile Virus is spread by the bite of an infected mosquito. They become

infected when they feed on infected birds. Infected mosquitoes can then

spread WNV to humans and other animals when

they bite.

House flies can spread Salmonella and E.coli. They

feed on fecal waste and transfer microbes from

their feet and other body parts to food.

Hepatitis B (HBV) H

BV

HBV is a viral infection that attacks the liver and can cause acute and chronic disease.

It can cause chronic liver disease and can lead to cirrhosis (scarring) of the liver and liver cancer

HBV is the most common serious liver infection in the world

HBV is an important occupational hazard for health workers

Page 138: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

HBV in The USA

138

HBV 3.5 – 5.3 million have chronic infection.

Many cases of HBV are not detected or reported to health departments

HBV is a leading infectious cause of death

Childhood vaccination programs led to 98% decline between 1990 – 2006 among children < 15years.

HBV in NYC

139

HBV Burden of chronic infection among adults remains large.

Each year the DOHMH receives about 11,500–13,000 newly reported cases.

67% of those with newly reported infection are largely due to immigration from highly endemic areas.

Hepatitis B Facts

140

HBV is 50 – 100 more infectious than HIV

Is very robust and can survive outside the body for at least 7 days

is most commonly spread from mother to child in highly endemic areas

can be asymptomatic; therefore, 2/3 of infected persons are unaware of their infection

most people recover and develop immunity within 6 months

5% of adults, 30-50% children, and 80 – 90% of infants develop chronic infection

Page 141: Health & Safety Training · Classification of Hazards BIOLOGICAL •viruses, parasite, bacteria, food, fungi, and mold CHEMICAL •depends on the physical, chemical and toxic properties

Transmission Period for Hepatitis B

141

Incubation period varies from 30 – 180 days

Average Incubation Period is 75 days

HBV can be detected 30 -60

days after infection

Even without symptoms, infected

persons can still spread HBV to other
