Safety is key in any workplace, but some are naturally more hazardous than others. Workplaces that handle dry powders carry unique hazards that employers need to consider and mitigate with safe handling practices.
Powder hazards
Dry powders can be combustible, potentially causing explosive clouds, while others can be toxic when inhaled, ingested, or even simply from skin contact. Other hazards include corrosivity and reactivity.
Safety measures
Anyone who is involved in handling dry powders should have training in how to do so safely. Employers should provide all necessary personal protective equipment and make sure it is readily available. PPE can include respirators, gloves, and goggles.
Think about how your dry powders are stored; for example, they should be kept in sealed containers in designated areas with clear labelling. Make sure the area is appropriate for the powder, as some may require cool, dry environments and others may need an inert atmosphere.
If the powders need to be moved, consider how to do this safely. You may need to use an advanced technological system, such as pneumatic conveying. If this is an appropriate solution, you can find out more from a specialist company such as https://www.aptech.uk.com/pneumatic-conveying-systems.
Make sure the areas where dry powders are present are properly ventilated to reduce the risk of explosion. You should also use anti-static materials and tools and eliminate ignition risks such as flames, hot surfaces, and sparks in areas where powders are used. Provide explosion protection measures such as suppression systems, flame arrestors, and explosion vents in areas of particular risk.
To ensure everyone is informed of the risks, have up-to-date safety data sheets available for all hazardous materials.
Emergency measures
While you should do everything possible to prevent an accident involving dry powders, you still need to be prepared for the event if it should occur. Have emergency protocols in place and review them regularly. Factors to consider in your plan include first aid measures, including easy access to a first-aider and first-aid equipment; evacuation routes in case of an explosion, fire, or contamination; and emergency contact numbers.
