Documenting Heat Illness Prevention Procedures

Whether you are covered by one or both of the outdoor or indoor heat illness prevention standards, you must establish, implement and maintain a written Heat Illness Prevention Plan. The plan can be included as part of your IIPP.¹ Employers covered by both outdoor and indoor heat illness prevention standards can create one plan to address procedures under both standards.

The plan, at a minimum, must contain the following:

• Procedures for provision of water. (See Providing Water).
• Procedures for providing access to shade or cool-down areas. (See Providing Shade).
