Engineering controls, such as COSHH cabinets, play a crucial role in containing hazardous substances and preventing exposure. Engineering controls can reduce exposure by as much as 80%, according to research by the National Institute for Occupational Safety and Health (NIOSH).
- Elimination: Removing the hazardous material altogether.
- Substitution: Replacing the hazardous material with a safer alternative.
- Engineering Controls: Implementing physical barriers or ventilation systems.
- Administrative Controls: Establishing safe work procedures and training programs.
- Personal Protective Equipment (PPE): Providing employees with appropriate PPE, such as gloves, respirators, and eye protection.
COSHH cabinet requirements: specifications and standards
COSHH cabinets are designed for secure hazardous substance storage, minimizing the risk of leaks, spills, and accidental exposure. To ensure their effectiveness for chemical storage safety, these cabinets must meet specific requirements and standards. Selection of the right COSHH cabinet is paramount for maintaining workplace safety, protecting personnel from the adverse effects of hazardous materials.
Construction materials
The materials used to construct COSHH cabinets must be appropriate for the substances being stored. Common materials include steel, coated steel, and certain types of plastics. Steel cabinets are generally suitable for storing flammable liquids, while plastic cabinets are often used for corrosive substances. The choice of material should be based on its resistance to the chemicals being stored, its fire resistance, and its overall durability. Selecting the wrong material can lead to deterioration of the cabinet and potential hazards. Consider that steel is often powder-coated with epoxy resin or similar for enhanced chemical resistance.
| Material | Properties | Suitable Substances | Considerations |
|---|---|---|---|
| Steel | High fire resistance, good structural strength, can be coated for chemical resistance. | Flammable liquids, solvents, paints. | Coating can be damaged, leading to corrosion; requires proper grounding. |
| Coated Steel | Enhanced chemical resistance, durable, good structural strength. | Acids, bases, solvents. | Coating integrity must be maintained; avoid scratches and abrasions. |
| Polyethylene (PE) | Excellent chemical resistance, lightweight. | Corrosive substances, acids, alkalis. | Lower fire resistance than steel; may not be suitable for flammable liquids. |
| Polypropylene (PP) | Excellent chemical resistance, good impact resistance. | Corrosive substances, acids, alkalis. | Lower fire resistance than steel; may not be suitable for flammable liquids. |
Ventilation
Ventilation is a critical aspect of COSHH cabinet design for chemical storage safety. Cabinets should be ventilated to prevent the buildup of hazardous vapors, which can pose a fire or health risk. Ventilation systems can be natural, using vents to allow air circulation, or forced, using fans to actively remove vapors. Forced ventilation is recommended for cabinets storing highly volatile substances. It is recommended to ensure there are regular air changes (typically 6-12 air changes per hour) to prevent the accumulation of hazardous vapors, adhering to standards like EN 14470-1.
- Natural Ventilation: Vents allow for air circulation.
- Forced Ventilation: Fans actively remove vapors.
- Extraction Systems: Connect cabinets to a central extraction system.
Leak and spill containment
COSHH cabinets must have a spill containment system to prevent hazardous substances from escaping in the event of a leak or spill. This typically involves a sump at the bottom of the cabinet, designed to contain the entire volume of the largest container stored within. The containment capacity should be clearly marked on the cabinet. Proper leak and spill containment minimizes the risk of environmental contamination and workplace accidents. According to EPA estimates, 15% of spills could be prevented with proper containment measures. EPA Spill Prevention
To calculate the required retention capacity, the general rule is that the sump should be able to contain at least 110% of the volume of the largest container, or 25% of the total volume stored in the cabinet, whichever is greater. For example, if the largest container is 20 liters, the sump should hold at least 22 liters. Ensure proper labeling to align with COSHH regulations for cabinets.
Security and closure
To ensure there isn’t any unauthorized access to dangerous substances, the COSHH cabinets should come equipped with a secure locking mechanism, such as a lock and key. The key should be kept in a secure place with the person or people responsible for the maintenance of the cabinet. Unauthorized access can lead to theft, misuse, or accidental exposure. Strong and reliable closures are critical to prevent accidental opening and spills. Some high-security cabinets use electronic access control.
