Hazardous Chemical:
- Hazardous material is a material which is capable of producing harmful physical and health effects.
- Harmful physical effects include fire, sudden release of pressure, explosion and other violent reactions.
- The chemicals which are labeled as per following category & symbol are considered to be Hazardous.
Harmful:
Harmful health effects includes acute and chronic condition. Flammable:
Liquids: Any Liquid having flash point below 100°F. Solids: Substance that can cause fire through friction, absorption of moisture or spontaneous chemical changes, when ignited will burn vigorously.
Oxidizing:
Substances which give rise to highly exothermic reaction in contact with other substances, particularly flammable substances.
Corrosive:
Substance which destroy living tissues. Toxic:
Substances so toxic that it presents risk to life or health. Explosive:
Chemical compound or mixtures that react, decompose with release of gas and heat. Dangerous to environment:
Substances which, were they to enter into the environment would present or might present and immediate pr delayed danger for one or more components of the environment.
Handling of Hazardous chemicals:
- While handling hazardous chemicals the QC personal should wear protective wear such as hand gloves, safety goggles, nose mask etc.
- Keep yourself away from container while pouring out the chemicals. Use suction bulb for pipetting the chemicals.
- While preparing dilute acid solutions take special care as follows. First cool the aqueous solution in ice bath. Slowly add acid into the solution with constant stirring.
- Keep inflammable liquids and substances away from naked flame or electric spark.
- Avoid breathing of vapors of spilled material.
