Laboratory and medical supplies include first aid, wound care, examination kits and equipments, and emergency eyewash and shower stations. These are used to provide medical assistance for a range of injuries. Supplies include antiseptics, ointments, CPR masks and medical wraps. Antiseptics and ointments disinfect wounds and protect against infection. CPR masks provide a barrier against contamination to keep first responders and patients safe. They fit over the patient's nose and mouth and contain a one-way valve. Medical wraps are sterile pieces of cloth that protect medical instruments during examinations and surgeries. They resist punctures, tears, fluids, particulates and lint.
