• Housekeeping : Maintain a clean jobsite. Use vacuum cleaners with high-efficiency particulate filters and use sweeping compounds or wetting agents for dust control when sweeping.

  • Scheduling : Sequence construction activities to reduce air quality problems. For renovation projects, coordinate construction activities to minimize or eliminate disruption of operations in occupied areas.

REQUIREMENTS EXPLAINED

Using established best practices during construction can protect construction workers from poor air quality and extreme heat.

The prerequisite requires projects to develop and implement construction management practices for the buildings’ construction and preoccupancy phases. The required practices are primarily adapted from the SMACNA IAQ Guidelines for Occupied Buildings under Construction, 2nd edition, 2007, ANSI/SMACNA 008–2008, Chapter 3. [105] The extreme heat requirement is adapted from OSHA prevention guidance for preventing heat-related illness. [106]

The practices must address all the following criteria:

No smoking Prohibiting smoking during construction supports a healthier and safer work environment. Smoking is a fire hazard. It creates odors and elevated levels of airborne contaminants that are associated with respiratory, cardiovascular, and other health problems. [107] Although cigarette smoking has declined among U.S. workers overall, its prevalence remains high among construction workers. [108] Prohibiting smoking is also beneficial for preserving the integrity and longevity of building materials that can absorb smoke, such as insulation and drywall.

Projects must prohibit smoking on the entire jobsite during the construction phase except in designated outdoor smoking areas. This applies to conventional cigarettes (cigarettes, cigars, pipes), cannabis (medical or recreational), and electronic smoking devices (e-cigarettes).
