Need to Evaluate Your Company’s Ergonomics Program? Check Out this New Safety Resource

MCAA believes that ergonomics should be a standard part of every company’s overall safety program. Recently MCAA partnered with The Center for Construction Research and Training (CPWR), Washington University in St. Louis, and Best Built Plans to develop and record a webinar on Creating a Contractor Ergonomics Program to Reduce Soft Tissue Injuries Among Construction Workers. The webinar is ideal for helping viewers understand the vital components of a successful ergonomics program, and why the components are so vital.


STOP USE! Miller MightEvac & MightyLite SRLs

Honeywell has issued an Immediate Stop USE Notice for certain models of Miller MightEvac and MightyLite self-retracting lifelines (SRLs) manufactured within a specific time frame. The notice only affects specifically listed models, with identified manufacturing dates or re-certification dates between October 27, 2016 and October 6, 2018. Models outside of this date range, including new units, are not affected by this notice. If your company uses these SRLs check Table 1 in the attached notice to determine whether your SRLs are affected. If so, they should be removed from service immediately. Honeywell is making arrangements for their return and replacement. That information is forthcoming.

Train Your COVID-19 Symptom Screeners with MCAA’s New Screener Training Resource

Are your company’s COVID-19 temperature and symptom screeners properly trained? To protect your company as much as possible from complaints, lawsuits, local labor issues, etc., it is critically important to:

  • Establish a consistent process for conducting such screening and excluding symptomatic individuals to promote workplace
  • Adopt measures to mitigate the risk of claims under laws related to discrimination and medical privacy; and
  • Be mindful of employee relations considerations.

Temperature and symptom screeners play an important role in accomplishing these objectives, so it’s a good idea to ensure that they are properly trained to take temperatures and screen for symptoms. MCAA’s new training resource, COVID-19 Temperature and Symptom Screener Training, will help you provide the proper training.

Revised CDC Guidelines for Discontinuing COVID-19 Isolation and Precautions

CDC Guidelines for Discontinuing COVID-19 Isolation & Precautions – For Non-Healthcare Settings – July 2020

Recent research indicates that individuals with mild to moderate cases of COVID-19 remain infectious no longer than 10 days after symptoms began; and individuals with severe illness or those who are severely immunocompromised remain infectious no longer than 20 days after symptoms began.

Based on these findings, the CDC has made changes to their guidelines regarding discontinuing COVID-19 isolation and precautions for non-healthcare settings. The highlights of these changes include the following:

  • Decision makers should use a symptom-based strategy for decision making. Using a test-based strategy is no longer recommended, except to discontinue isolation or other precautions earlier than would occur under the symptom-based strategy that follows.
  • Persons with COVID-19 who have symptoms and were directed to care for themselves at home may discontinue isolation under the following conditions:
    • At least 10 days have passed since symptom onset; and
    • At least 24 hours have passed since resolution of fever without the use of fever-reducing medications; and
    • Other symptoms have improved.
  • Infected individuals who never develop COVID-19 symptoms may discontinue isolation and other precautions 10 days after the date of their first positive real-time qualitative test for the virus.
  • The test-based strategy may still be appropriate for severely immunocompromised individuals. Consult with infectious disease experts for more information.

These recommendations will prevent most, but cannot prevent all, instances of secondary spread.

Prepare your workers for the hot summer days by providing them with the knowledge they need to prevent heat stress related illnesses.

Common heat stress related illnesses and accompanying symptoms include:

  • Heat Stroke: The body loses its ability to sweat, and can’t control its temperature (HEAT STROKE IS A MEDICAL EMERGENCY)
  • Heat Exhaustion: The body sweats away too much water and salt
  • Heat Syncope: The body’s blood pressure becomes too low, resulting in dizziness or fainting and
  • Heat Cramps: The body experiences painful muscle spasms.

MCAA Safety Resources Provide Training Talks

Caution Your Workers About Exposure to COVID-Disinfecting Chemicals

Some of the chemicals being used to disinfect jobsite surfaces can cause COVID-19 like symptoms in recently disinfected areas without adequate ventilation and/or other protective measures. MCAA recommends that you train all employees to ask appropriate onsite personnel whether chemical disinfection for COVID-19 has been performed recently in the areas they will be working. When chemicals have been recently used in those work areas, workers should request a Safety Data Sheet (SDS) for the chemical(s) to determine what the health hazards are, and how they can protect themselves. Once they have the SDS(s) they should pay special attention to Section 2 Hazard(s) Identification and Section 8 Exposure Controls/Personal Protection.

Critical Change to CDC’s Discontinuing Isolation Guideline

Based on new COVID-19 research the CDC has recently changed their guidelines regarding discontinuing isolation for individuals with symptoms of the virus who are caring for themselves at home. The original guidelines for discontinuing isolation specified that at least 7 days had passed since symptoms first appeared and, at least 3 days (72 hours) had passed since recovery. Recovery is defined as resolution of fever without the use of fever-reducing medications and improvement in respiratory symptoms (e.g., cough, shortness of breath). The CDC’s change increases the period of recommended isolation by 3 days, from 7 to 10 days after symptoms begin. Please be sure to change your company’s COVID-19 exposure control plans accordingly.


Worker has symptoms, but has not tested positive: Any employee who has not tested positive, but who exhibits symptoms of COVID-19 is required to stay off the jobsite until he or she is free of symptoms for 72 hours or more without the use of fever-reducing, or other symptom-altering medications.

Worker tests positive, but has no symptoms: Any employee who does test positive, but is symptom free may return to work when at least 10 days have passed since the date of his or her first positive test, and he or she has not had a subsequent illness. 

Worker tested positive, has symptoms and is caring for self at home: Any employees who does test positive and is caring for him or herself at home may return to work when at least 72 hours have passed since recovery, and at least 10 days have passed since the symptoms first appeared. 

Worker tested positive and has been hospitalized: Any employee who tests positive and has been hospitalized may return to work when permitted to do so by his or her medical care provider.


Alcohol-Based Hand Sanitizers Are Flammable

Using an effective hand sanitizer is one of the most important things everyone can do to help prevent the spread of COVID-19. This is especially true on construction jobsites and in mechanical service areas where there is no running water. To be effective against COVID-19, the CDC states that hand sanitizers must contain at least 70% alcohol. Since alcohol is flammable, we must be extremely careful when using it. Many things on a jobsite can serve as an ignition source, such as a lighter, a welding torch striker, welding and grinding sparks, even static electricity.
