Study Notes

Introduction to Occupational Safety and Health Standards

OSH standards are mandatory rules on occupational safety and health
They codify all safety orders
Objective of standards: Protect workers from occupational risks and hazards
Standards cover all workplaces, except mining safety

Good Housekeeping (5S)

Poor housekeeping is characterized by cluttered and poorly arranged areas
Untidily piling of materials
Improperly piled materials damage other materials
Items no longer needed
Blocked aisles and passagesways
Materials are stuffed in out-of-the-way places

Construction Safety

Safety personnel should connote a sound state of the body and mind, enabling normal work performance.
Safe or safety conditions refer to physical or environmental conditions, complying with standard provisions
Personal protective equipment (PPE) must be furnished

Tool Hazards

Hand and arm injuries: Caught by moving parts, cuts, burns
Body injuries: Fall from heights, drowning, low oxygen levels, hit by solid or sharp objects
Foot injuries: Falling objects, caught in between, struck by solid and sharp objects, stepping on sharp objects

Welding, Grinding, and Cutting

Approved equipment must be used
Cylinders must be constructed and marked according to recognized safety practices
Only qualified personnel should perform welding, grinding, or cutting
Areas for hot works must be fire-safe
Welding/cutting prohibited in flammable material areas

Ladder Safety

Ladders are best used for short-term tasks
Never move, shift, or extend a ladder while someone is on it
Avoid carrying objects or loads that will cause imbalance
Ladders should ideally extend 3 feet above upper landing

Machine Safety

Machines simplify tasks and transmit forces, motion, and energy
Hazardous mechanical motions: Cutting, punching, shearing, bending
Motions: Rotational, reciprocating, traversing

Lockout/Tagout

Lockout (LO): Physical restraining device
Tagout (TO): Warning/identification tag

Electrical Safety

Electrical code is adopted as the standard
Regional Offices have the power to issue and approve electrical installations and connections for service or power supply
Electrical plans are required

Fire Safety

OSHA regulations govern flammable liquids and gases
Fire safety planning and prevention measures are crucial

Industrial Hygiene

Industrial hygiene includes recognizing, evaluating, and controlling environmental factors in workplaces.
Chemical hazards include gases (Chlorine, Hydrogen, Ammonia, Carbon Monoxide), vapors (Benzene, Toluene, Acetone, Xylene), mists, fumes.
Physical hazards: Extreme temperature, radiation (ionizing and non-ionizing), extreme pressure, inadequate illumination, excessive vibration, noise
Biological hazards: Viruses, bacteria, fungi, parasites
Ergonomic hazards: Awkward body postures, prolonged standing, repetitive movements

Work Environment Measurement (WEM)

Determining the magnitude of hazards
Physically checking the environment (air quality, illumination, noise)
Testing for harmful substances to determine worker exposure
Monitoring worker exposure
