Proper storage of hazardous chemicals is critical for protecting workers, emergency responders, and the public from chemical exposures and accidents. As an employer or facility manager, compliance with Occupational Safety and Health Administration (OSHA) regulations for hazardous chemical storage is legally required to avoid citations and penalties. This article provides best practices and step-by-step guidance on safely storing hazardous chemicals while remaining in compliance with OSHA's hazardous chemical storage regulations.
Understanding OSHA Requirements for Chemical Storage
OSHA's hazardous chemical storage regulations are outlined in 29 CFR 1910 Subpart H. This standard applies to nearly all workplaces where employees use or store hazardous chemicals.
The key requirements include:
-
Hazard communication - Employers must maintain a written hazard communication program and provide training to employees on the safe handling of hazardous chemicals. Safety data sheets (SDS) must be maintained and accessible for all stored chemicals.
-
Container labeling - All containers of hazardous chemicals must be properly labeled with the identity of the chemical, hazard warnings, and the name/address of the manufacturer.
-
Storage compatibility - Incompatible chemicals must be stored separately to avoid dangerous reactions. OSHA mandates separation based on hazard classification.
-
Spill control - Adequate aisles and clearances must be provided for emergency access. Spill kits and containment measures are required.
-
Ventilation - Indoor storage areas require mechanical or natural ventilation systems. Storage rooms should be fire-rated and have automatic sprinklers.
-
Security - Storage areas must be secured against unauthorized access. Hazardous chemical quantities should be limited within storage areas.
Failure to comply with these requirements can result in OSHA inspections and monetary penalties for regulatory violations.
Best Practices for Compliant Chemical Storage
Here are some best practices to follow for safely storing hazardous chemicals in an OSHA-compliant manner:
Storage Area Design
-
Locate chemical storage areas away from high-traffic zones and emergency exits. Outdoor storage is preferred when possible.
-
Provide adequate ventilation - At least 6 air changes per hour are recommended for indoor storage rooms.
-
Install automatic sprinklers and use fire-rated walls in storage areas.
-
Include proper signage on doors to identify the hazardous chemical storage area. Signs should state restrictions, PPE requirements, and emergency contact info.
Storage Methods
-
Use OSHA-approved storage cabinets - Flammable liquid cabinets and corrosive storage cabinets meet OSHA standards.
-
Store chemicals on spill pallets or secondary containers to contain leaks. Shelving should have lips to prevent containers from sliding off.
-
Separate incompatible chemicals on different shelves and containment trays.
-
Limit container sizes based on fire codes and OSHA volume thresholds. Use no more than 5-gallon containers for flammable liquids.
-
Keep containers closed when not in use. Use ventilation devices when opening containers.
Administrative Practices
-
Maintain accurate inventory records of stored chemicals with up-to-date SDS.
-
Provide employee training on chemical hazards, safe handling, PPE, and spills/emergencies.
-
Inspect storage areas regularly to check for spills, leaks, expiring chemicals, and other issues.
-
Develop emergency plans for responding to chemical spills, fires, explosions, and releases. Coordinate with local emergency responders.
-
Follow proper disposal procedures for hazardous chemical wastes.
OSHA Inspections and Violations
To avoid OSHA violations and penalties, employers should self-inspect facilities and remain continually compliant with all applicable OSHA standards for hazardous chemical storage.
Common citation areas include:
- Incomplete hazard communication program or SDS records
- Improper container labeling
- Lack of PPE for chemical exposures
- Inadequate aisle space in storage area
- Chemical compatibility issues and improper separation
- Lack of sprinklers/ventilation in indoor storage
- Lack of proper spill containment
In the event of an OSHA inspection:
-
Designate a knowledgeable staff member to accompany the compliance officer.
-
Provide requested documents like SDS, training records, and inventory lists.
-
Explain all efforts to comply with standards and correct any deficiencies.
-
Take detailed notes and photos during the inspection.
-
Discuss possible abatement measures and timeframes if violations are found.
