4. Potential Hazards and Risks

Hazard	Risk	Control Measures
Chemical Exposure	Skin irritation, burns, respiratory problems, poisoning	Use appropriate PPE (gloves, goggles, respirators), work in well-ventilated areas, follow proper handling procedures 6, 12
Spills and Leaks	Slips, falls, environmental contamination, chemical reactions	Use secondary containment, clean up spills immediately, follow spill response procedures
Fire and Explosion	Burns, injuries, property damage	Store flammable chemicals properly, eliminate ignition sources, use grounded containers 2, 9
Incompatible Chemicals	Violent reactions, explosions, release of toxic gases	Store chemicals separately according to compatibility, consult SDS for storage guidelines
Improper Disposal	Environmental damage, health hazards	Follow proper waste disposal procedures, use designated containers, comply with regulations

5. Personal Protective Equipment (PPE)

Proper PPE must be worn at all times when handling chemicals to minimize the risk of exposure and injury 6, 12.

Gloves - Chemical-resistant gloves appropriate for the specific chemical being handled. Inspect gloves for punctures or tears before use. Change gloves immediately if contaminated .
Eye Protection - Safety glasses with side shields or chemical splash goggles to protect eyes from splashes, vapors, and particles. Use a face shield when there is a risk of severe exposure .
Respiratory Protection - Use a respirator when engineering controls are not adequate to control airborne concentrations. Ensure proper fit and training before use 6, 7.
Lab Coat/Apron - A chemical-resistant lab coat or apron to protect clothing and skin from contamination. Ensure the coat is buttoned and worn properly .
Closed-toe Shoes - Closed-toe shoes must be worn at all times in areas where chemicals are handled to protect feet from spills and dropped objects .

Inspect PPE before each use for damage or defects. Clean and store PPE properly after use. Replace damaged or worn PPE immediately .

6. Equipment and Tools

Use the appropriate equipment and tools for the task to ensure safety and efficiency .

Chemical Fume Hood - Use a chemical fume hood when working with volatile or hazardous chemicals to prevent exposure to vapors and fumes. Ensure the hood is functioning properly before use .
Secondary Containment - Use trays, tubs, or other secondary containment devices to contain spills and leaks .
Pumps and Transfer Devices - Use appropriate pumps or transfer devices for transferring liquids to avoid spills and splashes .
Designated Waste Containers - Use designated waste containers for the disposal of chemical waste. Ensure containers are properly labeled and compatible with the waste .
Hand Trucks/Carts - Use hand trucks or carts to transport heavy or bulky chemical containers safely .

Inspect equipment and tools before each use for damage or defects. Maintain equipment according to manufacturer's instructions. Remove any defective equipment from service .

7. Pre-Job Requirements

7.1 Training and Competency

All personnel must complete a chemical handling training program that covers the hazards of chemicals, safe handling procedures, PPE requirements, emergency procedures, and waste disposal 4, 5.

7.2 Pre-Job Briefing

Conduct a pre-job briefing before starting any chemical handling task to discuss the hazards, risks, and control measures. Review the SDS for each chemical involved and ensure everyone understands the procedure .

7.3 Work Area Preparation

Ensure the work area is clean, well-ventilated, and free of obstructions. Have all necessary equipment and PPE readily available. Ensure that safety equipment, such as eyewash stations and safety showers, are accessible and functioning properly .

8. Safe Work Procedure Steps

Step 1: Chemical Procurement and Transportation

Obtain chemicals from approved suppliers and ensure they are properly labeled and packaged. Use appropriate transportation methods to move chemicals safely within the facility .

Verify the identity and integrity of the chemical container.
Use a hand truck or cart for transporting heavy or bulky containers.
Ensure the transportation route is clear of obstructions.

Step 2: Chemical Storage

Store chemicals in a designated area according to compatibility and regulatory requirements. Ensure proper ventilation, temperature control, and security .

Segregate incompatible chemicals to prevent reactions.
Store flammable chemicals in approved flammable-liquid storage cabinets .
Date chemicals upon receipt and rotate stock to prevent the buildup of expired materials .
