HSE aims to reduce work-related death, injury and ill health. A very small sample of the specimen is placed on the slide and a cover glass is placed on top. Supplies Lab coat/gown Chemical goggles Chemically resistant gloves Aldex, available through eSHOP Tissue strainer Precautions If the specimens are too large, then one has to invest a bit of preparation time to make it suitable for observation. A worker's exposure to formaldehyde should not exceed this WEL and every effort should be made to reduce the exposure as low as is reasonably practicable, and in any case below the WEL. Designated persons may stop the leak and shut off ignition sources if these procedures can be done without risk. The organs of insects, for example, can be processed this way. Carolinas Perfect Solution is a proprietary product whose formulation is a protected trade secret, and we are unable to provide component information for disposal decisions; however, we can work with local authorities to verify that materials of special concern to them are not present in the solution.
