Chemical Exposure
A chemical hazard is any substance that can cause harm, primarily to
people. Chemicals of all kinds are stored in our homes and can result
in serious injuries if not properly handled

Chemical Exposure
Any hazard that results from the accidental, deliberate or potential release of a
noxious substance into the environment. An element or mixture of elements or
synthetic substances that are considered harmful to people.
Possible sources of chemical hazards include:
1.The burning of fossils, materials and chemicals used in construction and
industry, pollution of the environment and water supply, chemical spillages,
industrial accidents, and the deliberate release of toxic materials.
2.Household cleaning products such as bleach, paints, acids, solvents
especially chemicals in an unlabelled container (warning sign!), it can result
in harmful chlorine gas or hydrochloric acid if carelessly used.
3.Gases like acetylene, propane, carbon monoxide, helium and Gasoline fumes
from containers for lawnmowers or boats can result in major health hazards
if inhaled.

3. Absorption–the chemical soaks through the skin -Some chemicals can
pass through the skin into the body.

4. Injection-it can occur when a sharp object (needle) punctures the skin
and injects a chemical (or virus) directly into the bloodstream.

Chemicals have symbols to show their possible hazards. Chemicals are
grouped according to the types of effects they could have
Symbol & Name Effects
Corrosive
Chemical cause burns if it comes into contact with the
skin
