Overview
This template is a daily task checklist for underground crews working in heat, cold, or rapidly changing temperature conditions. It is built for pre-shift and mid-shift use, so the crew can verify the controls that matter most in the field: hydration, work-rest cycles, PPE adjustments, access to warming or cooling relief, and signs that a worker is starting to struggle.
Use it when the job exposes people to underground spaces, wet environments, winter openings, high exertion, or weather swings that can turn a manageable shift into a blocking safety issue. It is especially useful for utility repair, vault access, sewer work, trench support, and other jobs where the crew may be out of sight and away from easy relief. The checklist keeps the review atomic, so each item can be answered clearly and acted on immediately.
Do not use this template as a substitute for a full confined-space permit, medical evaluation, or site-specific heat illness/cold stress program. It is also not the right tool for office work, low-exposure inspections, or one-time incident investigations. The value of the template is in repeatable field execution: it turns temperature-stress awareness into a simple, auditable routine that helps the DRI spot blocking conditions before they become injuries or stoppages.
Standards & compliance context
- This template supports OSHA-style hazard recognition and control verification by documenting that crews checked exposure conditions before continuing work.
- It aligns with common heat illness and cold stress prevention practices by prompting hydration, rest, PPE, and symptom checks in a repeatable format.
- If your work includes confined-space entry, this checklist should complement, not replace, the required permit, attendant, and rescue procedures.
- Site rules, union agreements, and local safety policies may require stricter stop-work triggers than the checklist shows, and those should be reflected in the template.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
How to use this template
- Set up the checklist with 5 to 15 atomic items that match your site’s heat and cold exposure controls, and mark only truly safety-impacting items as critical.
- Assign a DRI such as the foreman or crew lead to run the checklist before the shift and again at the mid-shift review point.
- Walk through each checklist item in the field and verify hydration, rest breaks, PPE fit, warming or cooling access, and any crew member symptoms with a yes, no, or N/A answer.
- If any item is blocking, pause the affected work, document the issue, and create a follow-up task for the corrective action instead of leaving it as a note.
- Review the completed checklist at the end of the shift to confirm recurring issues, update controls for the next day, and adjust the checklist if site conditions changed.
Best practices
- Keep each checklist item specific and independently verifiable, such as verifying water supply, break timing, or PPE adjustment, rather than asking whether the crew is generally comfortable.
- Use normal priority for most items and reserve critical only for conditions that can affect safety or compliance, such as signs of heat illness, frostbite risk, or no access to relief.
- Run the checklist twice on long shifts: once before work starts and once when conditions, exertion, or weather have changed enough to alter exposure risk.
- Treat missing hydration, broken warming gear, or no cooling access as blocking issues that require immediate action, not as non-blocking notes.
- Document the DRI and the time of each review so supervisors can see who verified the controls and when the conditions were last checked.
- Include a verification step for crew symptoms, because early signs of heat or cold stress are easy to miss when workers are focused on production.
- Customize the checklist for the actual underground environment, such as wet vaults, winter street openings, or high-exertion digging, instead of using the same items for every job.

Common use cases
Frequently asked questions
Who should use this Underground Crew Daily Cold and Heat Stress Check template?
Use it for underground utility crews, trench and vault teams, sewer and stormwater crews, and any field supervisor responsible for workers exposed to temperature extremes. It works best when a DRI such as the foreman, lead hand, or safety lead runs the checklist before shift start and again mid-shift. If your crew rotates between hot, humid, cold, or wet underground conditions, this template helps keep the checks consistent.
How often should this checklist run?
Run it daily before the shift and repeat it mid-shift when conditions can change, especially during long jobs, weather swings, or heavy exertion. If your site has a formal heat illness or cold stress trigger, use this checklist whenever the trigger is met rather than waiting for the next scheduled review. The recurrence should match your operating pattern, not just the calendar.
What does this template actually cover?
It covers the practical controls crews need to verify before and during underground work: temperature exposure, hydration, work-rest cycles, PPE adjustments, warming or cooling access, and signs of stress in the crew. It is designed as a task checklist, so each item should be independently verifiable with a yes, no, or N/A answer. It is not a general safety audit or a full confined-space permit.
Is this a replacement for OSHA or company heat-stress procedures?
No. This template supports your existing safety program by turning policy into a repeatable field checklist. It helps crews document that they checked the conditions and applied the controls, but it does not replace required training, medical guidance, or site-specific procedures. If your organization has stricter rules, those should be reflected in the checklist items.
What are the most common mistakes when using this checklist?
The biggest mistake is making the items too broad, such as asking whether the crew is 'safe' instead of verifying hydration, shade, breaks, or PPE adjustments. Another common issue is treating every item as critical, which hides the few checks that truly affect safety or compliance. Teams also miss the mid-shift review and only complete the pre-shift pass.
How should the checklist be customized for different underground jobs?
Adjust the items to match the actual exposure risks on your site, such as wet vaults, refrigerated utility spaces, winter street openings, or high-exertion digging. You can add site-specific triggers for heat index, wind chill, or duration underground, and you can assign the DRI to the foreman, safety observer, or rotating crew lead. Keep each checklist item atomic so the crew can answer it without debate.
Can this template connect to other safety or operations workflows?
Yes. It pairs well with daily tailgate briefings, confined-space permits, PPE inspections, hydration logs, and incident follow-up tasks. Many teams link it to an ITIL-style runbook for weather-triggered work stoppage or to a Kanban board so blocking issues, like missing cooling gear or no warming shelter, are escalated immediately. That makes the checklist part of the workflow instead of a standalone form.
How does this compare with an ad-hoc verbal check?
A verbal check is easy to forget and hard to review later, especially when conditions change during the shift. This template creates a repeatable record of what was checked, what was blocked, and what action was taken. It also helps different supervisors apply the same standard instead of relying on memory or personal judgment.
