# NIOSH

NIOSH, the National Institute for Occupational Safety and Health, is the federal institute that researches work injury and illness and makes recommendations to prevent them. It is part of CDC.

NIOSH is the National Institute for Occupational Safety and Health. It is part of the Centers for Disease Control and Prevention. Its job is research and recommendations to prevent work-related injury and illness. It does not enforce rules. OSHA does that.

NIOSH publishes the heat stress guidance many safety programs follow, including its [acclimatization](https://jmarsolutions.multisites.ai/glossary/acclimatization) schedule and its advice on [work/rest schedules](https://jmarsolutions.multisites.ai/glossary/work-rest-schedule) and the [buddy system](https://jmarsolutions.multisites.ai/glossary/buddy-system). It also published the NIOSH Criteria for a Recommended Standard: Occupational Exposure to Heat and Hot Environments. Read how its advice fits employer duties in our [heat stress prevention guide](https://jmarsolutions.multisites.ai/heat-stress-prevention).
