Heat illness

This module records heat-illness prevention assessments, modelled on Cal/OSHA §3395. It computes the NWS heat index (Rothfusz regression) from temperature and humidity to set a risk band, and flags an assessment as deficient when a required provision is missing.

Record an assessment

1. Go to Heat illness and use the Record a heat assessment form at the bottom.
2. Pick the Site and Area, and enter the temperature (°F) and relative humidity (%).
3. Tick the provisions in place: drinking water, shade, rest/recovery periods, acclimatization plan, heat-illness training, and emergency response.
4. Click Record. The assessment joins the list with its computed heat index and risk band.

Read the triggers

• Shade trigger (80 °F): when the temperature or heat index reaches 80 °F, five provisions are required — drinking water, shade, rest/recovery periods, training, and emergency response. Rows at this level show a shade badge.
• High-heat trigger (95 °F): at 95 °F the acclimatization plan is required too, and the row shows a high-heat badge with an amber highlight.
• The risk band follows the NWS heat-index categories: minimal (below 80 °F), caution (80–89), extreme caution (90–102), danger (103–123), extreme danger (124 °F and above).
• An assessment missing any required provision is deficient (red row) and lists what's missing.

Close gaps

A deficient row shows a CAPA button — click it to open a corrective action for the missing provisions. Once raised, the row links to that CAPA.

What happens automatically

• The heat index and risk band are computed for you from temperature and humidity.
• The dashboard counts heat assessments, high-heat days, and deficient assessments.

Tip: reassess when conditions change through the day — the heat index, and therefore what's required, moves with the weather. Use the Site filter to review one location's history. The winter counterpart is cold stress.
