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.
