Heat-stress work/rest cycle + hydration + acclimatization plan — Los Angeles outdoor trades.

LA County runs one of the country's largest outdoor construction, landscaping, and roofing workforces, working through summer heat waves that regularly clear the WBGT thresholds where NIOSH work/rest limits tighten. California's own Title 8 heat-illness rule (Cal/OSHA Section 3395) already requires water, shade, and cool-down rests for outdoor work — but the highest-risk group, new hires and workers returning from time off, is exactly where a generic crew schedule fails: they have not acclimatized and the standard schedule is built for workers who have. A WBGT-based plan with an explicit acclimatization ramp closes that gap for the crew members most likely to be carried off the job site.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

heat-illness/medication screen + WBGT-and-workload reading + a work/rest cycle set from the NIOSH/ACGIH table + a hydration schedule + an acclimatization ramp for new/returning workers, with any current heat-illness symptom routed to EMERGENCY and any red flag routed to a clinician

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• WBGT meter or a validated on-site heat-index estimate (OSHA-NIOSH Heat Safety Tool app, or a site WBGT reading) for the shift
• the NIOSH/ACGIH WBGT-based work/rest and workload table (light/moderate/heavy metabolic rate x WBGT band)
• a hydration log (water intake and timing, electrolyte use) and a marked water source at the job site
• an identified shade/cool-down location at the job site
• an acclimatization tracking log (days on this job/site, workload percent, symptoms) for new or returning workers
• a clothing/PPE note (fabric, layers) for the WBGT clothing-adjustment factor

Steps

1. 1. Screen first: heat-illness history, cardiovascular or kidney disease, pregnancy, and any medication that impairs heat tolerance (diuretics, some cardiac or psychiatric medications). Anyone symptomatic right now (confusion, collapse, hot/dry or profusely sweating skin with altered mental status) STOPS the assessment immediately and routes to EMERGENCY (call 911) — do not proceed with planning.
2. 2. Record the worker's exposure status: days worked on this job or job site, and any absence of more than a week (illness, vacation, injury, seasonal layoff, weather shutdown). NIOSH/CDC surveillance places most occupational heat fatalities in the first days of heat exposure on a job, before the body has adapted (Bonauto 2017) — this status decides the acclimatization ramp below.
3. 3. Estimate or record the workday's WBGT (site meter reading, or the OSHA-NIOSH Heat Safety Tool app using local temperature and humidity), and classify the task's metabolic workload (light/moderate/heavy) and clothing.
4. 4. Look up the matching NIOSH/ACGIH work/rest ratio for that WBGT-and-workload cell and set the shift's work/rest cycle (minutes worked per hour vs. minutes resting in shade or a cool area). Unacclimatized, new, or returning workers use the lower, more protective action limit for that cell, never the full-exposure limit.
5. 5. Set a hydration schedule: about one cup (~237 mL) of water every 15-20 minutes of work in the heat, not exceeding roughly 1.5 L/hour or 12 L/shift (over-hydration risks exertional hyponatremia), with electrolyte replacement for sweating beyond about 2 hours or visibly heavy sweat loss.
6. 6. Build the acclimatization ramp for a new or returning worker: start at roughly 20% of the full workload/duration on day 1, increase by no more than about 20% per day, reaching full exposure over roughly 7-14 days. Hold or restart the ramp after any absence longer than a week.
7. 7. Record the WBGT/workload band, the work/rest cycle, the hydration schedule, the acclimatization day and ramp step, and a self-monitoring symptom checklist (cramps, heavy sweating, dizziness, nausea, headache = STOP, cool, hydrate; confusion, slurred speech, collapse, seizure, or hot/dry OR profusely sweating skin with altered mental status = EMERGENCY, call 911, cool immediately); sign.

What counts as done

• Completed heat-illness history / cardiovascular-kidney-pregnancy / medication screen (cleared, or routed to a clinician; any current symptom routed to EMERGENCY before proceeding)
• WBGT or validated heat-index estimate and task workload recorded for the LA job site, with the matching work/rest cycle set from the NIOSH/ACGIH table
• A hydration schedule (timing, volume, electrolyte trigger) and, for a new or returning worker, a recorded acclimatization ramp (day count, workload percent) matched to the LA summer heat-wave pattern
• A self-monitoring symptom checklist recorded, with the emergency route for confusion/collapse/altered-mental-status named explicitly

Proof is measured against these, not judged by taste.
