SEPTEMBER 22, 2020: COVID-19 Indoor Air Exposure: HVAC Precautions

I wanted to provide updates on evolving perspectives regarding indoor air and COVID-19, which is thought to spread mainly through close person-to-person contact. However, uncertainty remains regarding the relative importance of different routes of transmission. In addition to close contact with infected people and contaminated surfaces, there is growing evidence that COVID-19 may spread indoors via airborne particles. Changes to the operation of HVAC systems can reduce potential airborne exposures.

There are a number of helpful guidelines available, including the USEPA (, CDC (, OSHA (, and ASHRAE ( These guidelines recommend increased ventilation rates and fresh air make-up, modifying filtration systems, and more frequent and thorough maintenance. Building owners should be mindful that there are emerging air treatment technologies that remain unproven and should consult with experts before HVAC modifications.

Landmark works closely with mechanical engineers to evaluate HVAC systems and develop practical solutions. If you have any questions, please give me a call. #hvac #covid #building

JUNE 1, 2020: Landmark's Brandy Howard to Address the American Industrial Hygiene Conference & Expo Conference

We're pleased to share that Landmark’s Brandy Howard, CIH, CSP is speaking at the American Industrial Hygiene Conference & Expo (AIHce) conference being held virtually this year on June 2 at 8 am MDT.

Highlights of topics to be covered include:

  • Strategies used by the Smithsonian to safeguard the storage of specimens preserved in flammable liquids.

  • The Art Institute of Chicago’s use of inert gas fire protection systems within the Prints and Drawings department to protect their paper collections.

  • A review of inspections techniques for lead and asbestos in historical structures.

  • Case studies in worker exposures including preservation of specimens using formalin and arsenic-containing historical texts.

  • Fossilized collection preparation and exposures generated including crystalline silica.

  • Apothecaries and the hidden hazards in their collections.

MAY 20, 2020: Respiratory Protection Guidance

As Industrial Hygienists, we are asked how to safely control exposures to airborne contaminants. Proper and consistent implementation of respiratory protection procedures is key, yet challenging, due to several factors:

  • Improper fit or positioning of respiratory protection devices can reduce effectiveness or increase the potential for hand-to-face contact.

  • Misunderstanding of the protection capabilities provided by a dust mask can lead to overconfidence. A recent study by the American Chemical Society found that N95 masks filter out 85-99% of droplets, but this is highly dependent on aerosol size, emission rates and procedures for mask storage and cleaning.

  • Inconsistent use (or non-use) of respirators by different people in the same setting, whether due to lack of individual responsiveness or unclear requirements, can demotivate others.

Key considerations when using a cloth face covering are consistent application of policies regarding use, using masks with a snug fit that is also comfortable during activity, and training on mask use and sanitization. Mask use should always be in concert with administrative and engineering controls.

Please contact us if we can provide further safety tips to controlling exposures to airborne contaminants.

APRIL 15, 2020: Workplace Safety During COVID-19

We have been assisting our industrial and manufacturing clients with developing practical plans, or updating existing pandemic plans, for preparing workplaces for COVID-19. As many commercial, professional services, and tech companies require employees to work from home, manufacturers face the reality that their employees must work on site. The challenge is to maintain a safe workplace while meeting production requirements.

The basic tenets of an Infectious Disease Preparedness and Response Plan include the implementation of basic infection prevention measures, development of procedures for prompt identification and isolation of sick personnel, development of workplace flexibilities and protections, and implementation of controls. Workplace controls include engineering (e.g., installing physical barriers), administrative (e.g., establishing alternating days or extra shifts that reduce the total number of employees in a facility at a given time), safe work practices, and appropriate personnel protection equipment (PPE). A good general reference for background and context is the OSHA Guidance on Preparing Workplaces for COVID-19 (OSHA 3990-03 2020).

Please call me if you have any questions. We can also steer you to industry-specific guidance and best practices. #healthandsafety
