The purpose of this study was to investigate the components contributions of personal protective equipment on physiological strain in firefighters during exercise and recovery. Eight firefighters participated in trials in which various combinations of personal protective equipment components weighing from 1.3 to 15.1 kg were worn. The results showed that rectal temperature, changes in rectal temperature, mean skin temperature, heart rate, oxygen consumption and blood lactate concentration were smaller in conditions without boots (no-boots) than in other conditions with no helmet, gloves or self-contained breathing apparatus (P < 0.05). Increases in rectal temperature per unit mass of personal protective equipment were approximately twice as small in no-boots condition as the other conditions. These results suggest that the reduction of the boots' mass might be more efficient to alleviate heat strain of firefighters wearing personal protective equipment, rather than the reduction of the mass of self-contained breathing apparatus, helmet or gloves. ⋯ As firefighters’ protective boots induce greater physiological burden when compared with a helmet, gloves or self-contained breathing apparatus, personal protective equipment designers need to consider the improvement of boots in terms of mass reduction, improvement of thermal comfort and ease of doffing during recovery to alleviate physiological strain on firefighters.

The present outbreak of Ebola has health care professionals seeking guidance on isolation precautions for routine care and aerosol-generating procedures (AGPs). The most recent guidelines state that during AGPs, health care professionals should wear respiratory protection at least as protective as a National Institute for Occupational Safety and Health-certified fit tested N95 filtering face piece respirator or higher; for example, a powered air-purifying respirator (PAPR). ⋯ Training programs on proper donning and doffing of personal protective equipment and quality control systems need to be in place. Respiratory therapists are frontline during AGPs and need to be active in the decision making of the type of equipment chosen to protect them.

Practice Guideline Guideline
Guidance on the use of respiratory and facial protection equipment.
Infectious micro-organisms may be transmitted by a variety of routes, and some may be spread by more than one route. Respiratory and facial protection is required for those organisms that are usually transmitted via the droplet/airborne route, or when airborne particles have been artificially created, such as during 'aerosol-generating procedures'. ⋯ To address this issue, the Scientific Development Committee of the Healthcare Infection Society established a short-life working group to develop guidance. The guidance is based upon a review of the literature, which is published separately, and expert consensus.
