Study Notes
Chemical Safety Overview
- Ensuring protection against harm during chemical incidents, defined as unintended events that can expose individuals to chemical hazards.
Types of Hazards
- Safety Hazards: Conditions causing injury or illness.
- Physical Hazards: Potential harm without physical contact, e.g., noise, heat, slips.
- Chemical Hazards: Harmful substances upon exposure, such as flammable or toxic chemicals.
- Ergonomic Hazards: Environmental factors that affect the musculoskeletal system, including poor posture.
- Psychological Hazards: Environmental aspects impacting mental health.
- Biological Hazards: Biological agents posing health risks, including viruses and bacteria.
Risk Assessment
- Risk is determined by the probability of harm from exposure to hazards, calculated as: Risk = Hazard x Exposure x Vulnerability.
Hazard Communication
- GHS Labeling: Standardized system for chemical classification and labeling.
- Includes product name, signal, precautionary symbols, hazard statements, supplier identification, and supplemental info.
Hazard Symbols and Meanings
- Health Hazard: Serious health effects (e.g., cancer).
- Flame: Flammable materials and gases.
- Exclamation Mark: Irritants and sensitizers.
- Gas Cylinder: Pressurized gases that may explode.
- Corrosion: Corrosive substances harming metals and skin.
- Exploding Bomb: Explosive materials.
- Flame Over Circle: Oxidizers enhancing combustion.
- Environment: Hazardous to aquatic life.
- Skull and Crossbones: Toxic or fatal substances.
NFPA Diamond
- A system indicating hazard levels, with higher numbers indicating greater danger.
Safety Data Sheet (SDS)
- Contains 16 sections detailing safety and health information about substances:
- Identification, hazard identification, composition, first-aid measures, fire-fighting measures, accidental release, handling/storage, exposure controls, physical/chemical properties, stability/reactivity, toxicological information, ecological information, disposal considerations, transport information, regulatory info, and other relevant data.
Hazard Control Recommendations
- Utilization of Personal Protective Equipment (PPE) such as:
- Eye and face protection
- Respiratory protection
- Hand and arm protection
- Foot and leg protection
- Torso protection
Regulatory Framework
- RA 11058: Act enhancing compliance with Occupational Safety and Health standards.
Common Exposure Routes
- Inhalation: The most prevalent route of chemical exposure, often involving gases and vapors.
- Prohibition of eating or drinking in areas with toxic materials enforced by the OSHA Sanitation Standard.
