First aid kits are useful to almost any industry, since the Occupational Safety and Health Administration (OSHA) requires all workplaces to make first aid equipment readily available in case of emergency. The container must be clean and waterproof to keep out bacteria. They should also be checked regularly to make sure all the equipment is present, up to date, and ready to be used. The contents vary according to context, since every industry has different occupational hazards but most are designed to treat minor injuries. Contents typically include adhesive bandages, antiseptic wipes, latex gloves, scissors, an emergency blanket, gauze and disinfectant. Even basic first aid kits intended for the workplace can be creatively improvised in emergency situations. After all, the first step to promoting health and safety in the workplace is by mapping out and obtaining a plan and supplies.
