Study Notes
General Safety
- Purpose of the Occupational Safety and Health Ordinance is employee protection at work.
- Employers and employees share responsibility for workplace safety; both must prioritize safety and health.
- Proprietors must ensure safe working environments, provide safety information, training, and supervision, and ensure safe access to workspaces.
- Chemical exposure routes include swallowing, skin contact, and inhalation; proper handling is critical.
- Proper identification of chemicals requires reading labels, which must include a chemical name, classification, risks, and safety precautions.
- Chemicals are classified as explosive, oxidizing, flammable, toxic, harmful, corrosive, and irritant; protective gear is essential when handling.
- Construction site safety practices include:
- Proper storage of materials and avoidance of floor openings.
- No throwing materials from heights or working near edges without guardrails.
- Keeping passageways clear and addressing timber hazards.
- Use of eye protection during welding.
- Avoid working under suspended loads.
- Construction sites with 5+ workers need a designated first aid box with appropriate markings and resources.
- For 30-99 workers, a trained first aid responder is required; 100+ workers necessitate a full-time safety officer.
- Employers must provide potable water and report dangerous occurrences to the Labour Department within 24 hours.
- "Mandatory Safety Training" must be recognized by the Commissioner for Labour.
Work at Height
- Fatal accidents in construction often occur from working at height; prioritize using working platforms for safety.
- Only trained personnel should erect scaffolds, which must be inspected by a competent person and certified safe every two weeks.
- Safety features of working platforms include guardrails to prevent falls and toeboards to keep objects from falling.
- Minimum working platform width is 400mm; guardrail height ranges from 900-1150mm, and toeboards must be at least 200mm tall.
- Safety harnesses must be secured to suitable anchorages or independent lifelines when used to prevent falls.
- For scaffold maintenance at heights, an independent lifeline is the best anchorage method; harness should be attached above waist level.
- At least 3 bolts are required to secure each metal bracket of truss-out scaffolds to buildings.
- Ladders must be stable, placed on solid ground, and should not be joined; they must extend at least 1.0 meter above the landing.
