Although the print version of The Synergist indicated The IAQ Investigator's Guide, 3rd edition, was already published, it isn't quite ready yet. We will be sure to let readers know when the Guide is available for purchase in the AIHA Marketplace.
 
My apologies for the error.

Disadvantages of being unacclimatized:
  • Readily show signs of heat stress when exposed to hot environments.
  • Difficulty replacing all of the water lost in sweat.
  • Failure to replace the water lost will slow or prevent acclimatization.
Benefits of acclimatization:
  • Increased sweating efficiency (earlier onset of sweating, greater sweat production, and reduced electrolyte loss in sweat).
  • Stabilization of the circulation.
  • Work is performed with lower core temperature and heart rate.
  • Increased skin blood flow at a given core temperature.
Acclimatization plan:
  • Gradually increase exposure time in hot environmental conditions over a period of 7 to 14 days.
  • For new workers, the schedule should be no more than 20% of the usual duration of work in the hot environment on day 1 and a no more than 20% increase on each additional day.
  • For workers who have had previous experience with the job, the acclimatization regimen should be no more than 50% of the usual duration of work in the hot environment on day 1, 60% on day 2, 80% on day 3, and 100% on day 4.
  • The time required for non–physically fit individuals to develop acclimatization is about 50% greater than for the physically fit.
Level of acclimatization:
  • Relative to the initial level of physical fitness and the total heat stress experienced by the individual.
Maintaining acclimatization:
  • Can be maintained for a few days of non-heat exposure.
  • Absence from work in the heat for a week or more results in a significant loss in the beneficial adaptations leading to an increase likelihood of acute dehydration, illness, or fatigue.
  • Can be regained in 2 to 3 days upon return to a hot job.
  • Appears to be better maintained by those who are physically fit.
  • Seasonal shifts in temperatures may result in difficulties.
  • Working in hot, humid environments provides adaptive benefits that also apply in hot, desert environments, and vice versa.
  • Air conditioning will not affect acclimatization.

BACTERIA AND VIRUSES
COVID-19 and Worker Fatigue
New routines and behaviors such as adhering to stay-at-home orders, wearing masks, and social distancing are constant reminders of our “new normal” and have been shown to increase anxiety. Terms such as “caution fatigue” and “quarantine fatigue” have emerged to describe the weariness we feel about our new restrictive circumstances as a result of the COVID-19 pandemic.
PERSONAL PROTECTIVE EQUIPMENT
Decontamination and Reuse of PPE in Healthcare
Given the current environment, it is important to understand PPE reuse and extended-use guidance that has been shared by OSHA, CDC, and other United States governmental entities. Research, testing, and guidance for the use and reuse options are changing rapidly and will need to be monitored on an ongoing basis.
COMMUNICATION AND TRAINING
Changing the World, One Course at a Time
Underlying the prevalence of occupational disease, injuries, and fatalities is the lack of adequately trained occupational hygienists who can not only anticipate, recognize, evaluate, and control occupational hazards, but confirm their controls. Based on this pressing need, OHTA was formed in 2010 by a group of international colleagues.
LABORATORIES
How to Recruit Researchers to Lab Safety
This article is the second in a series begun by James Stubbs and Mahdi Fahim’s “Fixing Lab Safety Failures” in the August 2020 issue of The Synergist. Here, Ashley Augspurger and Diana Harrington Peroni focus on labs that lack a good safety culture, and those that maintain a poor safety culture.
Demographics of Healthcare Workers with COVID-19
Healthcare workers who die from COVID-19 are more likely to be older, male, Asian, Black, or have an underlying medical condition than healthcare workers who survive the disease, according to a report published in September by CDC.

A Tribute to Fred Toca
Fred Toca has long been recognized as a pioneer and expert in the field of environmental health, on matters such as industrial hygiene management, chemical exposure, toxicology, regulatory interpretation, and exposure assessment.

AIHA, CSHS Publish Guidance on Leading Health Metrics
A new guidance document, "Best Practice Guide for Leading Health Metrics in Occupational Hygiene," is intended to help OEHS professionals use leading health metrics to identify health concerns and hazards, prevent exposure, and control risk in the workplace.

DUST
A New Tool for Preventing Combustible Dust Incidents
From the February 2020 issue: Central to the 2019 edition of NFPA 652, Standard on the Fundamentals of Combustible Dust, is the requirement for owners or operators of facilities with potentially combustible dust to conduct a Dust Hazard Analysis. The standard sets a deadline of Sept. 7, 2020, for completion of the DHA.
BACTERIA AND VIRUSES
No Boundaries
From the April 2018 issue: As the incidence of highly hazardous communicable diseases continues to rise, all relevant professionals, including industrial hygienists, should be involved in prevention efforts, training and education for occupations with potential exposure, and advocacy for increased federal support.
HEALTHCARE
Protecting Home Healthcare Aides
From the April 2019 issue: Providing care in the home is one of the most cost-effective and efficient mechanisms for maintaining patient health, but home healthcare workers are among the most vulnerable workers in the United States.
