Editing Biological hazard (section)

==ANSI Z535/OSHA/ISO regulation==
Biohazardous safety issues are identified with specified labels,{{efn|See [[Globally Harmonized System of Classification and Labelling of Chemicals]] for chemical labelling standards for containers.}} signs and paragraphs established by the American National Standards Institute (ANSI). Today, [[ANSI Z535]] standards for biohazards are used worldwide and should always be used appropriately within [[ANSI Z535]] Hazardous Communications (HazCom) signage, labeling and paragraphs. The goal is to help workers rapidly identify the severity of a biohazard from a distance and through colour and design standardization.{{citation needed|date=March 2023}}

Biological hazard symbol design:
* A red on white or white-coloured background is used behind a black biohazard symbol when integrated with a DANGER sign, label or paragraph.
* An orange on black or white-coloured background is used behind a black biohazard symbol when integrated with a WARNING sign, label or paragraph.
* A yellow on black or white-coloured background is used behind a black biohazard symbol when integrated with a CAUTION sign, label or paragraph.
* A green on white or white-coloured background is used behind a black biohazard symbol when integrated with a NOTICE sign, label or paragraph.

DANGER is used to identify a biohazard that will cause death. WARNING is used to identify a biohazard that may cause death. CAUTION is used to identify a biohazard that will cause injury, but not death. NOTICE is used to identify a non-injury biohazard message (e.g. hygiene, cleanup or general lab policies).

OSHA requires the use of proper ANSI HazCom where applicable in American workplaces. States and local governments also use these standards as codes and laws within their own jurisdictions. Proper use of ANSI Z535 signs, labels and paragraphs are written into many of OSHA's standards for HazCom and crafted to integrate with ISO symbols.
