Physical hazards refer to factors in the work environment that can cause harm without necessarily changing the chemical composition of a substance. Examples of physical hazards include noise, vibration, radiation, temperature extremes, and ergonomic factors such as repetitive motion or awkward postures.

Chemical hazards, on the other hand, refer to substances that can cause harm due to their chemical properties. These substances may be in the form of liquids, gases, vapors, dusts, or fumes. Examples of chemical hazards include toxic chemicals, flammable materials, corrosive substances, and carcinogens.

In summary, physical hazards are related to the physical conditions of the work environment, while chemical hazards are related to the chemical properties of substances present in the workplace. Both types of hazards can pose risks to workers and should be properly identified and managed to ensure a safe work environment.

Physical Hazards

- Definition: Hazards that can cause physical injury without causing a chemical reaction.
- Types:
- Ergonomic hazards: Awkward postures, repetitive motions, vibration, noise.
- Environmental hazards: Heat, cold, radiation, air pollution, noise.
- Mechanical hazards: Machinery, tools, moving objects, falls.
- Electrical hazards: Electricity, lightning, electrical equipment.
- Fire hazards: Flammable materials, ignition sources.

Chemical Hazards

- Definition: Hazards that involve chemicals that can cause adverse health effects through skin contact, inhalation, or ingestion.
- Types:
- Toxic substances: Chemicals that can damage organs or systems in the body.
- Irritants: Chemicals that cause irritation to skin, eyes, or mucous membranes.
- Sensitizers: Chemicals that can cause allergic reactions.
- Carcinogens: Chemicals that can cause cancer.
- Mutagens: Chemicals that can cause mutations in DNA.
- Teratogens: Chemicals that can cause birth defects.

Key Differences

- Nature: Physical hazards involve physical forces or energy, while chemical hazards involve chemical substances.
- Exposure pathways: Physical hazards typically affect the body through physical trauma, while chemical hazards can enter the body through inhalation, skin contact, or ingestion.
- Effects: Physical hazards can cause immediate physical injury, while chemical hazards can have both acute and long-term health effects.
- Immediate danger: Physical hazards often pose an immediate danger due to their potential for immediate injury, while chemical hazards may have delayed effects.
- Control measures: Control measures for physical hazards focus on preventing exposure to physical forces or energy, while control measures for chemical hazards focus on minimizing exposure to hazardous chemicals.
