• Struck-by hazards: This refers to injuries caused by being struck by falling objects, swinging loads, or moving vehicles. Hard hats, safety glasses, and adherence to traffic rules within the workplace are necessary precautions.
• Electrical hazards: Exposure to electricity can lead to severe injury or death. Proper grounding, insulation, lockout/tagout procedures, and regular equipment inspections are vital to prevent electrical hazards.
• Noise hazards: Prolonged exposure to loud noise can cause hearing loss. Hearing protection, noise reduction measures, and regular hearing tests are crucial components of a noise hazard control program.
• Vibration hazards: Exposure to excessive vibration can lead to hand-arm vibration syndrome (HAVS) or whole-body vibration syndrome (WBVS). Using anti-vibration tools, reducing exposure time, and regular health checks are vital preventative steps.
• Temperature extremes: Exposure to extreme heat or cold can cause heat stroke, hypothermia, or frostbite. Proper personal protective equipment (PPE), acclimatization procedures, and scheduled breaks are crucial measures.
• Radiation hazards: Exposure to ionizing or non-ionizing radiation can have harmful health effects. Shielding, distance, and time limitation are important strategies for radiation hazard control.

2. Chemical Hazards

Chemical hazards encompass substances that can cause harm through ingestion, inhalation, absorption, or injection. These can include:

• Corrosive chemicals: These chemicals can burn skin and damage internal organs. Proper handling procedures, PPE such as gloves and eye protection, and adequate ventilation are critical safety measures.
• Toxic chemicals: These substances can cause harm through inhalation, ingestion, or absorption. Material Safety Data Sheets (MSDS) provide essential information on safe handling and emergency response procedures.
• Flammable and combustible materials: These substances can easily ignite and cause fires or explosions. Proper storage, handling procedures, and fire safety training are essential precautions.
• Reactive chemicals: These are substances that can react violently with other chemicals, causing fires, explosions, or the release of toxic gases. Strict segregation, compatibility assessments, and proper handling procedures are critical.
• Carcinogenic chemicals: These chemicals are known or suspected to cause cancer. Minimizing exposure, using engineering controls, and implementing strict safety procedures are essential.

3. Biological Hazards

Biological hazards involve living organisms that can cause illness or injury. This includes:

• Bacteria: Bacteria can cause a wide range of infections and diseases. Proper hygiene, sanitation, and vaccination are key preventative measures.
• Viruses: Viruses can cause various illnesses, some of which can be serious or fatal. Vaccination, hygiene practices, and infection control procedures are vital.
• Fungi: Fungi can cause infections of the skin, lungs, or other organs. Proper ventilation, hygiene, and control of moisture are important preventative steps.
• Parasites: Parasites can cause a variety of diseases and infections. Hygiene, sanitation, and pest control are crucial preventative measures.
• Bloodborne pathogens: These pathogens are transmitted through contact with infected blood or body fluids. Proper hygiene, use of PPE, and safe handling of sharps are vital to prevent transmission.

4. Ergonomic Hazards

Ergonomic hazards relate to the design of the workplace and the way tasks are performed. These can lead to musculoskeletal disorders (MSDs). Common ergonomic hazards include:

• Awkward postures: Prolonged bending, twisting, or reaching can strain muscles and joints. Proper workstation setup, job rotation, and stretching breaks are crucial preventative measures.
• Repetitive motions: Repeated movements can lead to repetitive strain injuries (RSIs). Ergonomic tools, work simplification, and regular breaks are key elements of prevention.
• Forceful exertions: Using excessive force to lift, push, or pull objects can cause injuries. Proper lifting techniques, mechanical aids, and job redesign are crucial preventative steps.
• Contact stress: Prolonged pressure on body parts can lead to injuries. Proper padding, cushioning, and workstation design are important preventative measures.
• Vibration hazards: Prolonged exposure to vibration can lead to hand-arm vibration syndrome (HAVS) or whole-body vibration syndrome (WBVS). Using anti-vibration tools, reducing exposure time, and regular health checks are vital.

5. Psychosocial Hazards

Psychosocial hazards relate to stress, workplace violence, and other factors that affect mental health and well-being. These hazards include:

• Workplace violence: This can range from verbal abuse to physical assault. Zero-tolerance policies, training programs, and security measures are essential preventative steps.
• Stress: Excessive stress can lead to burnout, depression, and other mental health problems. Stress management training, employee assistance programs, and creating a supportive work environment are vital.
• Harassment and bullying: These behaviors can create a hostile work environment and negatively impact mental well-being. Clear policies, reporting mechanisms, and training are critical to address these hazards.

Methods for Identifying Hazards

Several methods can be used to identify hazards effectively:

• Walkthrough inspections: Regularly conducting walkthroughs allows for visual identification of potential hazards.
• Job hazard analysis (JHA): JHAs involve a systematic examination of a job to identify potential hazards.
• Safety audits: Comprehensive safety audits provide a more detailed assessment of workplace safety.
• Incident investigation: Investigating incidents can uncover underlying hazards that may not have been previously identified.
• Employee input: Encouraging employees to report hazards is crucial as they often have firsthand knowledge of potential dangers.
• Near-miss reporting: Reporting near-miss incidents allows for the identification and correction of potential hazards before they lead to accidents.

Control Measures for Hazards

Once hazards are identified, appropriate control measures should be implemented. The hierarchy of controls is a crucial concept:

1. Elimination: This involves removing the hazard entirely.
2. Substitution: This replaces the hazard with a less hazardous alternative.
3. Engineering controls: These are physical changes to the workplace to reduce hazards (e.g., machine guarding, ventilation systems).
4. Administrative controls: These involve changes to work practices, training, or procedures.
5. Personal protective equipment (PPE): This is the last line of defense and should only be used when other controls are not feasible.
