Study Notes

Hazard Types

Concealed: Not immediately obvious (e.g., electricity, toxic vapors).
Developing: Becomes apparent over time (e.g., worn tires, cables).
Transient: Intermittent or temporary (e.g., machinery overload, expired permits).
Behavioral: Human actions creating hazards (e.g., horseplay, leaving objects in pathways).

Incident Causation

Unsafe Behaviors: Operating without authority, failing to warn, working at unsafe speeds, making safety devices inoperative, using unsafe equipment, using unsafe postures, working on moving/energized equipment, horseplay, failure to use PPE.
Unsafe Conditions: Improper guarding, defective equipment, inadequate warning devices, hazardous arrangement or storage, improper illumination, improper ventilation.

Health Hazards

Physical: Noise, heat, radiation, vibration, pressure, machinery, electricity.
Chemical: Gases, vapors, acids, alkali, poisons, aerosols, irritants.
Biological: Pathogens, fungi, micro-organisms.
Psychosocial: Stress, social problems, accidents, fear of failure, retrenchment.
Ergonomic: Workplace design, workstation layout, excessive manual handling, tool design.

Safety Hazards

Mechanical: Cuts, entanglement.
Heights: Falling objects.
Electrical: Shock, burns.
Fire/Explosion: Burns, injury, death.
Confined Space: Poisoning.

HIRAC

Hazard Identification: Process to identify hazards (e.g., risk analysis, workplace inspection, safety audits, job safety analysis, feedback from workers, observations, specialist advice, accident records, MSDS/CSDS).
Risk Analysis: Assessment of the possibility of injury or harm from a hazard.

Risk Definition

Risk: The chance of being harmed or experiencing an adverse health effect when exposed to a hazard.
Severity: The adverse effect of a hazard on a worker.
Likelihood: The chances of a hazard occurring.

Risk Rating Matrix

Low Risk: Existing controls sufficient; no additional action needed unless risk increases.
Moderate Risk: Further action required to minimize risk.
High Risk: Immediate action is necessary to minimize risk. Continuously review and manage the risk.

Risk Assessment

Prioritizing hazards into groups.
Selecting groups for risk elimination, reduction, and control.

Risk Control

Measures to eliminate or reduce the risk of exposure to a hazard.

Control Measures

Elimination or Inactivation: Stopping the hazard at the source (engineering controls), along the path to the worker (administrative controls), or at the worker level (PPE, least desirable).
Risk Elimination: Best solution, however, not always practical (e.g., substituting lead-based paint with water-based paint).
Risk Minimization: Reducing the number of people exposed or the intensity of exposure to the hazard.
Substitution: Changing hazardous materials with safer alternatives.

Engineering Controls

Redesign: Modifying equipment or processes to eliminate or reduce hazards.
Barriers: Physical barriers to separate workers from hazards.
Isolation: Enclosing or separating hazardous areas or equipment.
Absorption: Using materials to absorb hazardous energy.
Automation: Using machines to replace manual tasks that pose risks.
Dilution: Reducing the concentration of hazards in the air.

Monitoring Controls

Ongoing evaluation of the effectiveness of control measures.

HIRAC Sample

Example Process: Alkali Preparation (ER)
Potential Hazard: Heavy lifting of materials exceeding 25 kg.
Identified Hazard: Disc bulged, muscle strain.
Risk Level: Low (Likelihood 2, Severity 1).
Control Measures: Proper lifting techniques training, maximum weight limit of 25 kg for bags.

Review and Check

Reviewing the effectiveness of the safety risk management process and evaluating new hazards or technology.

Principles of Risk Management

Accept and consider all risks.
Prioritize risks based on their level (high, moderate, low).
Manage risks effectively.
Integrate risk management into all planning activities.

Benefits of JSA/HIRAC

Improve quality, maintain a healthy workforce, reduce injury and illness rates, increase acceptance of high-turnover jobs, boost employee morale, reduce worker’s compensation costs, and assist with regulatory compliance.

Your Role in Safety

Participate in safety training.
Report hazards, incidents, and near misses.
Maintain a safety attitude.
Ask for help.

General Safety Rules

Obey all warning signs.
Follow all safety procedures.
Do not take shortcuts.
Do not engage in horseplay.
Use common sense.

Identifying Safety Hazards

Be observant for safety hazards.
Fix what you can.
Report what you can’t fix.
Offer suggestions for safety improvements.

Good Housekeeping

Keep work areas well-maintained.
Encourage a safe environment.
Practice 5S compliance (sort, set in order, shine, standardize, sustain).

Fire Response

Know the location of fire extinguishers.
Use the right extinguisher for the job.
Know how to use an extinguisher (pull the pin, aim at the base of the fire, squeeze the trigger, sweep back and forth).

Accident Response

Summon professional help (or inform supervisor).
Contact the in-house emergency contact.
Provide emergency first aid.
Report the incident.
Maintain proper records.
Cooperate with the investigation.

Electrical Hazards

DO: Use plugs that fit the outlet, check wire and cord insulation, ensure electrical connections are tight, keep flammables away from outlets, keep clear access to electrical boxes.
DON’T: Overload outlets, fasten chords with staples or nails, run cords through water, touch cords with wet hands, use damaged cords, use ungrounded cords or remove the grounding prong from a three-pronged plug.

Key Points

Play your role in safety and security.
Look for and report hazards.
Use common sense.
Respond safely to emergencies.
Follow workplace safety procedures.
