Department: [DEPARTMENT NAME]
1. Scope
This safe work procedure (SWP) outlines the guidelines for the safe handling, storage, and disposal of hazardous chemicals in compliance with OSHA and EPA regulations. It applies to all personnel who handle or may be exposed to hazardous chemicals in the workplace. This SWP aims to minimize the risks associated with chemical exposure, prevent incidents, and ensure a safe working environment.
2. Definitions
Hazardous Chemical Any substance or mixture that is a physical hazard or a health hazard as defined by the Hazard Communication Standard (29 CFR 1910.1200). SDS (Safety Data Sheet) A document that provides information on the properties of hazardous chemicals and how they affect health and safety in the workplace. PPE (Personal Protective Equipment) Equipment worn to minimize exposure to hazards, including eye protection, gloves, and protective clothing. Spill Kit A collection of materials and equipment used to contain and clean up spills of hazardous chemicals. Secondary Containment A system designed to prevent spills from escaping into the environment, such as double-walled tanks or spill pallets.
3. Responsibilities
3.1 Supervisors
- Ensure that all workers are adequately trained on the hazards of chemicals they work with and how to respond to a spill. [2]
- Provide appropriate personal protective equipment (PPE) and ensure its proper use and maintenance.
- Ensure that spill kits are available, well-stocked, and located near work areas. [2]
- Enforce all safety rules and procedures related to hazardous chemical handling, storage, and disposal.
3.2 Workers
- Follow all safety rules and procedures outlined in this SWP.
- Use the appropriate PPE as required and inspect it before each use.
- Report any spills, leaks, or other incidents immediately to the supervisor.
- Participate in all required training programs.
4. Potential Hazards and Risks
| Hazard | Risk | Control Measures |
|---|---|---|
| Chemical Spills [1] | Exposure to hazardous chemicals through skin contact, inhalation, or ingestion. | Use secondary containment, proper storage, and spill kits. |
| Inhalation of Vapors [9] | Respiratory irritation, dizziness, or other health effects from inhaling chemical vapors. | Use adequate ventilation, respiratory protection (e.g., respirators), and vapor control measures. |
| Skin Contact [7] | Skin irritation, burns, or absorption of harmful substances through skin contact. | Wear appropriate chemical-resistant gloves and protective clothing. |
| Eye Contact [9] | Eye irritation, burns, or vision damage from chemical splashes. | Wear safety glasses or goggles and face shields when handling chemicals. |
| Fire and Explosion | Fire or explosion from flammable chemicals. | Store flammable chemicals in approved containers and areas, control ignition sources, and ensure proper ventilation. |
| Mixing Incompatible Chemicals [3] | Violent reactions, release of toxic gases, or explosions. | Never mix incompatible chemicals. Refer to SDS for compatibility information. |
| Improper Disposal [1] | Environmental contamination and regulatory violations. | Dispose of chemical waste according to local, state, and federal regulations. |
| Lack of Training [2] | Improper handling and increased risk of incidents due to inadequate knowledge. | Provide comprehensive training on chemical hazards, handling, storage, disposal, and emergency procedures. |
5. Personal Protective Equipment (PPE)
Proper PPE is essential for protecting workers from chemical hazards.
- Chemical-Resistant Gloves: Nitrile or neoprene gloves appropriate for the specific chemicals being handled. Ensure gloves are inspected for tears or punctures before use. [4] [9]
- Safety Glasses or Goggles: Safety glasses with side shields or chemical goggles to protect eyes from splashes or vapors. [8]
- Face Shield: A face shield provides additional protection for the face and eyes, especially when handling large quantities of chemicals or when there is a risk of splashing. [5]
- Chemical-Resistant Apron or Coveralls: Protective clothing to prevent skin contact with chemicals. [10]
- Respirator: A NIOSH-approved respirator with appropriate cartridges for the specific chemicals being handled, if ventilation is inadequate. [9]
- Safety Shoes or Boots: Chemical-resistant safety shoes or boots to protect feet from spills and punctures. [8]
Inspect PPE before each use for damage or defects. Replace damaged PPE immediately. Clean and maintain PPE according to manufacturer's instructions.
6. Equipment and Tools
All equipment and tools used for handling hazardous chemicals must be in good working order and inspected regularly.
- Spill Kit: A portable kit containing absorbent materials, PPE, and clean-up tools for chemical spills. [2]
- Secondary Containment: Spill pallets or trays to contain leaks and spills from containers. [1]
- Chemical Storage Cabinets: Cabinets designed for the safe storage of flammable or corrosive chemicals.
- Ventilation System: Local exhaust ventilation to remove chemical vapors from the work area.
- Drum Handling Equipment: Dollies or forklifts for moving heavy drums of chemicals.
7. Pre-Job Requirements
7.1 Training and Competency
Training and Competency: All employees who handle hazardous chemicals must receive comprehensive training on chemical safety, including hazard communication, PPE use, spill response, and waste disposal. [8]
7.2 Pre-Job Briefing
Pre-Job Briefing: Conduct a pre-job briefing to discuss the specific hazards, PPE requirements, and procedures for the task at hand.
7.3 Work Area Preparation
Work Area Preparation: Ensure the work area is clean, well-ventilated, and free of obstructions. Have spill control materials readily available.
8. Safe Work Procedure Steps
- Pre-Job Inspection: Inspect all PPE, equipment, and work area to ensure everything is in good condition and ready for use.
- Chemical Handling: Wear appropriate PPE. Handle chemicals carefully to avoid spills or splashes. Use dispensing equipment as necessary.
- Chemical Storage: Store chemicals in designated areas, ensuring proper segregation of incompatible substances. Keep containers tightly closed and labeled.
- Spill Response: In the event of a spill, immediately alert others in the area. Don appropriate PPE from the spill kit and contain the spill using absorbent materials. [6]
- Waste Disposal: Collect chemical waste in properly labeled containers. Dispose of waste according to local, state, and federal regulations. [1]
- Decontamination: After handling chemicals, thoroughly wash hands and any exposed skin with soap and water. Decontaminate PPE as necessary.
9. Precautions and Safety Measures
- Always read and understand the SDS for each chemical before handling.
- Ensure adequate ventilation in the work area.
- Never eat, drink, or smoke while handling chemicals.
- Store chemicals in properly labeled containers.
- Regularly inspect chemical storage areas for leaks or spills.
10. Emergency Procedures
10.1 General Emergency Response
In any emergency, the primary concern is the safety of all personnel. [1]
10.2 Specific Emergency Scenarios
- Chemical Spill on Skin: Immediately flush the affected area with water for at least 15 minutes. Remove contaminated clothing and seek medical attention if irritation persists. [6]
- Chemical Spill in Eye: Flush the eye with water for at least 15 minutes, holding the eyelid open. Seek immediate medical attention. [6]
- Chemical Inhalation: Move to fresh air immediately. If breathing is difficult, administer oxygen and seek medical attention.
- Fire Involving Chemicals: Activate the fire alarm and evacuate the area. Use a fire extinguisher appropriate for the type of chemical fire, if trained and safe to do so.
11. Incident Reporting and Investigation
All incidents, including spills, leaks, near-misses, and exposures, must be reported immediately to the supervisor. [1]
A thorough investigation will be conducted to determine the root cause of the incident and implement corrective actions to prevent recurrence.
