Study Notes

Hazard Classification

Hazard severity is classified using a numerical scale from 0 to 4, where 4 indicates extremely hazardous materials.

Chemical Hazard Identification System

Classifies hazards into four categories:
- Reactivity/Stability Hazard
- Specific Hazard
- Health Hazard
- Fire/Flammability Hazard

Hazards Color Coding

Yellow: Represents Reactivity/Stability Hazard.
White: Indicates Specific Hazard.
Blue: Designates Health Hazard.
Red: Signifies Fire/Flammability Hazard.

Reactivity/Stability Hazard Index

Scale is as follows:
- 0: Stable
- 1: Unstable if heated
- 2: Violent chemical change
- 3: Shock and heat may deteriorate/detonate
- 4: May deteriorate/detonate

Specific Hazard Codes

Codes for specific hazards include:
- OXY: Oxidizer
- ACID: Acid
- ALK: Alkali
- COR: Corrosive
Additional note: Use no water and be aware of radiation hazards.

Health Hazard Index

Scale includes:
- 0: Normal Material
- 1: Slightly Hazardous
- 2: Hazardous
- 3: Extreme Danger
- 4: Deadly

Flammability Hazard Index

Scale includes:
- 0: Will not burn
- 1: Burns above 200°F
- 2: Burns below 200°F
- 3: Burns below 100°F
- 4: Burns below 73°F

Degree of Hazards (Hazard Index)

Classifies materials based on hazard severity:
- 0: No or minimal hazard
- 1: Slight hazard
- 2: Moderate hazard
- 3: Serious hazard
- 4: Extreme/Severe hazard

Electrical Safety Precautions

Avoid operating equipment with wet hands (True).
All electrical equipment should be fitted with a 3-pronged plug for grounding to prevent electric shock.
If electrical shock occurs, avoid touching the person or the equipment involved (False).

Emergency Response to Electric Shock

Immediate actions when someone suffers electric shock:
- Turn off the circuit breaker.
- Unplug the equipment if safe to do so.
- Move equipment using a non-conductive material, such as glass or wood.

Storage of Flammable Chemicals

Flammable chemicals must be stored in safety cabinets and explosion-proof refrigerators located in remote areas to minimize risk.
