Controlling COVID-19 in the Workplace

Apply the Hierarchy of Controls

Use multiple preventative practices, starting from the most effective, in a layered approach. In all cases wear masks, practice physical distancing, hand hygiene, and respiratory etiquette.

Elimination and Substitution

• Allow workers to work remotely where and if possible.
• Assess the need to report to the workplace in person on an individual or job role basis.
• People with immunocompromising health conditions (including chronic conditions such as diabetes, heart and lung issues, or cancer) or who live with immunocompromised individuals may need to continue to work remotely.
• Use technologies to facilitate working remotely, such as teleconferencing.

Engineering Controls

• Physical barriers
• Increased ventilation and high efficiency filters
• Sensors or no- or low-touch controls for water taps, doors, and garbage lids

Administrative Controls

• Communicate risks and rules.
• Limit occupancy, stagger shifts/teams.
• Use electronic communications for sign-ins and administrative work.
• Screen workers, visitors, and customers.
• Clean and disinfect surfaces and objects on a routine schedule. Disinfect high-touch surfaces as necessary.
• Practice the greatest possible physical distancing, hand hygiene and respiratory etiquette.
• Change work practices to encourage physical distancing.

Personal Protective Equipment

• Respirators
• Face shields
• Gowns
• Eye Protection

Masks

• Non-medical masks are NOT personal protective equipment.
• Follow guidance from your local public health authority about when and how to use a mask.
• Wearing a non-medical mask or face covering is recommended when you cannot consistently keep 2 metres away from others, especially in crowded settings.
• If your mask becomes damaged, wet or dirty, replace it with a fresh one.
• Wearing a mask alone will not prevent the spread of COVID-19, but it can help. Continue to follow personal prevention practices.
