It is about chemical safety how to handle chemicals and how we aware about chemical hazards

1. Chemical hazard
• A chemical accident is the unintentional release of one or more hazardous
substances which could harm human health or the environment. Chemical
hazards are systems where chemical accidents could occur under certain
circumstances. Have two type Physical and Health
• An element or mixture of elements or synthetic substances that are considered
harmful to employees.
• Chemical hazards may be described under three broad headings - flammability,
reactivity and health.

2. Chemical hazards
• Chemicals can affect the skin by contact or the body either
through the digestive system or through the lungs if air is
contaminated with chemicals, vapors, mist or dust. There can
be an acute (immediate) effect, or a chronic (medium to long-
term) effect from the accumulation of chemicals or substances
in or on the body.

5. Flammability
• Flammable substances are those that readily catch fire
and burn in air. A flammable liquid does not itself burn;
it is the vapors' from the liquid that burn.

6. Reactivity
• Reactive chemical hazards invariably involve the release of energy (heat) in
relatively high quantities or at a rapid rate.
• Some chemicals decompose rapidly when heated. Light or mechanical shock can
also initiate explosive reactions.

7. Health
• Contact with many chemicals can result in adverse health
effects.

8. hazardous chemicals
• Categories of hazardous chemicals:
• Flammable or explosive
• Gasoline, kerosene
• Irritating to skin, lungs, eyes
• Strong acids, strong alkali (lye), paint fumes
• Interfere with oxygen uptake, delivery, and use in body
• Carbon monoxide, Hydrogen sulfide, cyanide
