New permanent rules for outdoor heat exposure go too far

The Department of Labor and Industries has proposed troubling new permanent rules for outdoor heat exposure. BIAW members work hard to protect our employees from health and safety risks on the job, but these rules go too far, resulting in difficult work schedules for employees and slowing down construction at the height of a housing crisis.

As part of the rulemaking process, L&I must gather stakeholder feedback. This is our chance to help improve these rules for workers, current and future homeowners and the building industry.

Among other things, the proposed rules:

  • Apply year-round whenever workers are exposed to outdoor heat
  • Affect workers in “non-breathable” clothes at 52°F and in all other clothing at 80°F, down from 89°F under current rules
  • Require employers to provide enough shade for all employees
  • Impose a 14-day monitoring requirement for employees not acclimatized to the heat, including new employees, those returning from absences, and all workers during a heat wave.
  • Mandate 10-minute rest breaks every two hours at 90°F or above and 15-minute breaks every hour at 100°F and above

Good intentions, difficult to implement

Recognizing the building industry should take appropriate action to protect workers from heat-related issues, we have some concerns about the rules as written and encourage builders, remodelers and others to weigh in with their own concerns.

The 80°F trigger temperature is very low, especially in eastern Washington during the summer.

We recommend L&I consider different trigger temperatures depending on the region. Some areas are more acclimatized than others.

No consideration in the rule for individuals already acclimatized prior to starting a job.

Workers who live in Yakima already are used to 80-plus-degree temperatures because they live it every day.

  • Why would these workers need 14-day monitoring?
  • Why would a person who left a job for seven days, but stayed in the same climate zone need to be re-acclimatized?
  • How are employers supposed to recognize whether an employee has become acclimatized?  They are not medical experts.
  • What happens when an employer believes that a worker is acclimatized, but the employee disagrees?

Unlimited rest breaks are ripe for abuse with no recourse for an employer.

While employers support the need to rest as needed in hot weather, we fear employers will be subject to labor law violations if they do not allow unlimited rest breaks. When other workers can’t rely on their team to complete their work, it puts everyone in jeopardy.

Alternative work schedules conflict with local noise ordinances.

The department suggests construction companies consider alternative work schedules to avoid working during the hottest part of the day. Sadly, in many jurisdictions, noise ordinances will prevent working before 8 am.  We propose working with local governments to allow early work on days when a company expects temperatures to exceed trigger levels. This should supersede any local ordinance if worker safety is a priority.
