• Coveralls: Flame-retardant coveralls protect technicians from hot exhausts, electrical sparks, and spilled fluids during diagnostics and repairs.
• Ear Protection: Used when operating pneumatic tools, compressors, or working near running engines to prevent hearing loss.
• Respirator Masks: Worn during spray painting, cleaning with solvents, or in dusty environments to prevent respiratory problems.

Characteristics of Effective PPE

• Durability: PPE must withstand workshop conditions, frequent use, and exposure to oils and chemicals.
• Proper Fit: Ill-fitting PPE undermines protection and may cause discomfort or accidents.
• Compatibility: PPE should not interfere with other equipment, such as safety goggles fitting well with helmets.
• Visibility: High-visibility elements on coveralls or helmets help prevent accidents in busy workshops.
• Ease of Maintenance: PPE should be easy to clean and inspect, encouraging regular upkeep and reducing contamination risks.

Typical Mistakes in PPE Selection

• Using generic gloves instead of chemical-resistant gloves for battery handling, exposing technicians to acid burns.
• Wearing ordinary shoes rather than safety boots, leading to foot injuries when heavy tools fall.
• Choosing non-flame-retardant coveralls in welding areas, increasing fire risk.

1.1.2 Legal Requirements for PPE Usage under OSHA 2007

The Occupational Safety and Health Act (OSHA) 2007 is Kenya's primary legislation governing workplace safety, including PPE use in automotive workshops. Compliance with OSHA is both a legal and ethical responsibility for employers and employees.

OSHA 2007 Provisions on PPE

• Mandatory Provision: Employers must supply PPE suitable for identified workplace hazards, such as gloves for chemical handling and goggles for welding.
• Correct Use: Employees are required to use PPE as instructed and not misuse or neglect it.
• Training: Employers must provide training on the correct selection, fitting, use, and maintenance of PPE.
• Supervision: Supervisors must ensure PPE is worn consistently and correctly during tasks.
• Reporting Deficiencies: Employees must report damaged or unsuitable PPE immediately to supervisors.
• Record Keeping: Employers should document PPE issuance, training, and inspections for evidence of compliance.
• Enforcement: Failure to comply with PPE requirements can result in fines, suspension, or prosecution under OSHA.

Importance of Legal Compliance

• Prevents Workplace Injuries: Proper PPE use reduces incidents, protecting workers and limiting liability.
• Promotes Professionalism: Compliance demonstrates commitment to safety and quality among technicians.
• Avoids Legal Penalties: Workshops face fines or closure if found in violation of OSHA standards.
• Enhances Reputation: Adherence to legal requirements reassures clients and partners of workshop safety standards.
• Supports Insurance Claims: Documentation of PPE use strengthens claims in case of accidents.

Site Tips

• Keep OSHA posters and PPE guidelines visible in the workshop to remind staff of legal requirements.
• Conduct regular briefings on PPE updates, especially when introducing new equipment or chemicals.

1.1.3 Proper Usage of PPE According to Designated Purpose

Using PPE as intended is crucial for its effectiveness. Each item is designed for specific hazards; misuse can lead to injuries or reduce protection.

Steps for Correct PPE Usage

1. Identify Task Hazards: Assess risks such as electrical shocks, chemical spills, or flying debris before starting work.
2. Select Appropriate PPE: Match the PPE type to the hazard, such as using goggles for grinding and gloves for battery handling.
3. Inspect PPE Before Use: Check for damage, wear, or contamination that could compromise safety.
4. Fit PPE Properly: Adjust straps, laces, or fastenings to ensure a secure and comfortable fit.
5. Use PPE Throughout the Task: Wear PPE for the entire duration of hazardous work, not just during specific steps.
6. Avoid Modifying PPE: Do not alter or remove parts of PPE, as this can invalidate protection.
7. Follow Manufacturer Instructions: Use PPE as directed in manuals or labels for maximum safety.
8. Report Issues Immediately: Inform supervisors if PPE is defective, uncomfortable, or inadequate for the task.

Examples of Correct Usage

• During vehicle diagnostics involving live electrical circuits, technicians wear insulated gloves and safety goggles as specified in the workshop’s safety manual.
• When spray painting, respirator masks are fitted according to manufacturer instructions, preventing inhalation of harmful fumes.

Watch Out For

• Removing gloves or goggles mid-task exposes technicians to sudden hazards, such as splashes or sharp edges.
• Using PPE intended for another purpose, such as gardening gloves in chemical handling, increases risk.

1.1.4 Maintenance and Storage of PPE According to Manufacturer’s Specifications
