Chemical Hygiene

Under the OSHA Chemical Hygiene Standard of 1990, chemicals that are in kits or contain less than 1% of a hazardous chemical do not have to be listed or treated differently. Many of the stains and reagents come in kits and rarely contain any chemical that is more that 1%. One colleague asked specifically about the Hematek packs. Under OSHA's definition they are considered a kit. They can remain on the shelf until they are opened and put on the machine where they remain until the pack is empty.
