NIOSH reviewed infectious disease investigations in workplaces across the U.S. and found infectious disease cases seem to be concentrated in healthcare industries and certain occupations, including lab, animal and public service workers. Work-related cases were associated with a variety of pathogens, but NIOSH found bacteria to be responsible in most cases reported. Researchers also identified reports of some pathogens such as; Ebola virus, lymphocytic choriomeningitis virus, norovirus, bacillus anthracis and Yersinia pestis, (re)emerging. Workplace factors can pose biologic hazards to workers. Additionally, individual worker characteristics may have a factor in increased risk of acquiring and transmitting infectious diseases. Researchers at NIOSH stress the possibility of other occupations possibly also being at risk. Read the full article in The Synergist.


Legionnaires ’ Disease Cases Continue to Rise

BY: Gerry Luther

A five-fold increase in the number of Legionnaires’ disease cases have been seen since 2002.
“Most healthcare facilities were mandated to perform risk assessments for Legionella sources and implement water management plans to prevent disease caused by Legionella and other waterborne
pathogens in June 2017. However, these efforts have not yet resulted in abatement of the upward trend in disease.” “New requirements and an emerging standard of care for operators of buildings and cooling towers to prevent conditions that lead to out-breaks of Legionnaires’ disease, the ongoing increase in cases should prompt all stakeholders to reevaluate their programs and operations.”
“Legionnaires’ Disease Cases Continue to Rise.” The Synergist, Apr. 2019, p. 26.

Caliche has been requested to conduct testing for Legionella in a variety of locations to include a confinement unit, college dormitories, water cooling systems, refinery, and onboard maritime vessels. Corrective action included increased vigilance to include routine testing of water systems, recommended treatment, follow-up assessments and awareness training for the maintenance and water treatment staff.

Caliche’s Industrial Hygienists, Occupational Health Physician, and technicians are available to assist our clients should the need arise.

OSHA Reveals Latest Top 10 List of Violations at NSC 2019

BY: Michael Luther

Patrick Kapust, deputy director of OSHA’s Directorate of Enforcement Programs, presented the
agency’s top 10 violations during the National Safety Council Congress Expo. OSHA’s preliminary data covering violations cited between October 1, 2018 and August 31, 2019.

The top 10 violations are:
1. Fall protection general requirements (construction)— (29 CFR 1926.501): common violations under this standard included failure to provide fall protection near unprotected sides or edges and on both low-slope and steep roofs.
2. Hazard communication (29 CFR 1910.1200): Common deficiencies include lack of a written
program, inadequate training, and failing to properly develop or maintain safety data sheets (SDSs).
3. Scaffolds (construction)—general requirements (29 CFR 1926.451): Common violations included
improper decking, failing to provide guardrails where required, and failure to ensure that supported
scaffolds are adequately supported on a solid foundation.
4. Lockout/tagout (29 CFR 1910.147): Many employers cited under this standard failed to establish an energy control procedure altogether, while others were cited for failing to provide adequate
employee training, failing to conduct periodic evaluations of procedures, and failing to use
lockout/tagout devices or equipment.
5. Respiratory protection (29 CFR 1910.134): Failing to establish a program, failing to perform required fit testing, and failing to provide medical evaluations were among the most frequently cited issues.
6. Ladders (construction) (29 CFR 1926.1053): Common deficiencies included failure to have side rails extend 3 feet (ft) beyond a landing surface, using ladders for unintended purposes, using the top step of a stepladder, and ladders with structural defects.
7. Powered industrial trucks (29 CFR 1910.178): Violations commonly addressed deficient or damaged forklifts that were not removed from service, failing to safely operate a forklift, failing to retain certification of training, and failing to evaluate forklift drivers every 3 years as required.
8. Fall protection training requirements (construction)— (29 CFR 1926.503): Commonly cited issues include failing to provide training to each person required to receive it, failing to certify training in writing, inadequacies in training leading to the failure of retention by the trainee, and failing to retrain in instances where the trainee failed to retain the training content.
9. Machine guarding (29 CFR 1910.212): Violations included failing to guard points of operation, failing to ensure that guards are securely attached to machinery, improper guarding of fan blades, and
failing to properly anchor fixed machinery.
10. Personal protective and lifesaving equipment (construction)—eye and face protection (29 CFR
1926.102): Commonly cited issues included failing to provide eye and face protection where
employees are exposed to hazards from flying objects; failing to provide eye protection with side
protection; and failing to provide protection from caustic hazards, gases, and vapors.

Four Misunderstandings about Gas Detection That Could Cost You

BY: Michael Luther

If you depend on a gas monitor, be sure you have the education and training to properly and appropriately operate gas detection instruments and to react to instrument readings.

Here are four (4) common misunderstandings about gas detection which could have serious consequences.

  1. “OL” or “OR”: These do not mean “OK.”
    1. “These are indications that the sensor has “pegged out”, reached its over limit (OL) or over
      range (OR).” Seeing this reading from a diffusion gas detector indicates exposure to that
    2. The “over” reading means you may be in an environment that could support an explosion.
  2. The “2 X 2” rule: Take your time.
    1. “When using a gas detector with tubing…the rule calls for two minutes of sampling time PLUS two seconds for every one foot of tubing attached to the monitor.”
  3. Bump testing: You can’t avoid it.
    1. “Bump tests check sensor and alarm functionality and are the only way to ensure your monitor is working properly. Without daily bump testing, your monitor could fail to alert you to gas hazards.”
  4. Calibration: The key to accuracy:
    1. If a gas detector is not regularly calibrated, readings will gradually change over time. Manufacturers recommend calibrating monthly.
