Rising Temperatures Also Raise Concerns for Workersprint this article

As heat warnings have been posted across Canada this summer, concerns for those who must work in hot environments have also risen. Factor in the COVID-19 pandemic and the additional issues around personal protective equipment, non-medical masks, and ventilation, and these rising temperatures can pose a serious challenge for workplaces. Preventing and recognizing heat stress is essential to avoiding heat stroke and other illnesses. Workers who are exposed to extreme heat or work in hot environments can be at risk of heat stress.

Outdoor workers at risk include firefighters, farmers, construction workers, agricultural workers, landscapers, mail carriers and others. Indoor settings such as greenhouses, bakeries, restaurants, and any workplace that generates heat as part of their process, or any workplace whose cooling system struggles to keep up with the soaring temperatures outside, also place workers at risk.

Heat Stress and Heat Stroke

Exposure to extreme heat at work can result in occupational illnesses and injuries. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes. Heat can also increase the risk of injuries in workers resulting from the hazards created by sweaty palms, fogged-up safety glasses, and dizziness.

Symptoms

Awareness of the symptoms and indicators of heat stress are a shared responsibility between workers and employers. In an increasingly hot work environment, workers may feel increased irritability, have difficulty concentrating, or lose the ability to perform skilled tasks or heavy work.

Heat exhaustion is often accompanied by feelings of nausea, heavy sweating, headache, muscle cramps, dizziness, and fatigue. Heat exhaustion and fainting (syncope) are types of heat related illnesses which are not fatal but they are still dangerous in that interfere with a person's ability to work safely.

In a very hot environment, the most serious health and safety concern is heat stroke. Heat stroke can be fatal if medical attention is not available immediately. The victims of heat stroke are often unable to notice the symptoms when they are happening to themselves, so their survival depends on their co-workers' ability to identify symptoms and get medical help.

While symptoms can vary from person to person, the warning signs of heat stroke can include complaints of sudden and severe fatigue, nausea, dizziness, light-headedness, and may or may not include sweating. If a co-worker appears to be disorientated or confused, or has unaccountable irritability, malaise or flu-like symptoms, the worker should be moved to a cool location and receive medical help immediately. Those who are 65 years of age or older, are overweight, have heart disease or high blood pressure, or take medications that may be affected by extreme heat are at a still greater risk of heat stress.

Prevention

Employers should provide training to workers so they understand what heat stress is, how it affects their health and safety, and how it can be prevented. Because people are generally unable to notice their own heat stress-related symptoms, it is important that everyone is educated on how to recognize symptoms and seek timely first aid and medical help.

Employers can protect workers from heat stress by avoiding heavy exertion tasks, extreme heat, sun exposure, and high humidity when possible. Guidance for hot workplaces includes providing plenty of drinking water. Workers should drink a cup every 15 to 20 minutes. Any increase in workload should be gradual and increases in temperature taken into consideration.  Provide breaks to rest and cool off, preferably in a cool area, in the shade or in air-conditioned buildings or vehicles. If working outdoors, umbrellas, buildings, and trees can also shield workers from the rays of the sun. Keep in mind that you will still need to maintain physical distancing when possible, so limiting the number of workers gathered at any one time or using markings or signs may be necessary. Additional shade shelters may be necessary.

Note that COVID-19 can spread in any climate, including hot and humid conditions. It is important to wash hands often, avoid touching your face, and cough or sneeze into the bend of your arm or a tissue.

Personal protective equipment (PPE) can increase body temperature or discomfort in the heat. Make sure outdoor workers wear light, loose-fitting clothing, UV-rated sunglasses, and a wide-brim hat. Provide sunscreen with a sun protection factor (SPF) of at least 30 and UVA/UVB protection and allow workers to re-apply every 2 hours and after sweating. The sun is strongest between 11am and 4pm so less strenuous tasks are more suited to this time.

Indoors or outdoors, give workers regular breaks where they can hydrate and remove their PPE or non-medical masks while still maintaining their physical distance from others. Avoid getting masks wet, as wet masks allow more air and small particles through than dry masks. It may be necessary to use more than one mask per day, depending on the work being done.

For indoor environments, employers should increase the air intake of the ventilation system and avoid central air recirculation where possible. Make sure that all air conditioning and ventilation systems are inspected and in good operational condition to help prevent transmission of COVID-19. If fans must be used, minimize air blowing from one person to another to reduce any potential airborne spread.

Review your existing heat stress plan to take into consideration measures to reduce and prevent the spread of COVID-19. Involve your health and safety committee, if you have one, or a representative when assessing workplace risks, and when determining appropriate controls, personal protective equipment, and training.

First Aid

If a worker has experienced heat stroke or heat exhaustion move them to a cooler, shaded location that is physically distant from other workers. Remove as much clothing as possible, including socks and shoes. Cool them down by applying cool wet cloths or ice to the head, face, or neck and spray with cool water. If a worker likely has heat exhaustion, help them drink water, clear juice, or a sports drink if they are able. If the person does not start to feel better call 911 for emergency help and stay with the person until help arrives.

If the worker may have heat stroke, help them cool down as above but do not force the person to drink liquids. Call 911 immediately if heat stroke is suspected.  Heat stroke is a medical emergency.

Tips & Tools

Limit Your Risk of Exposure to COVID-19 with the ArriveCAN Appprint this article

The Government of Canada has put in place emergency orders under the Quarantine Act. It applies to all travellers arriving in Canada. Its purpose is to slow the spread of COVID-19 in Canada. Travellers entering Canada by air or by land must provide basic information and undergo a screening by a border services officer or quarantine officer to assess symptoms.

Download the ArriveCAN app

Use this mobile app to speed up your arrival process in Canada and spend less time with border and public health officers. Submit your information easily and securely via the app within a 48 hours window before arriving in Canada. The app helps you to:

  • provide mandatory information that is required for entry into Canada
  • avoid lineups and reduce points of contact at the border
  • provide updates on your quarantine compliance and the development of any symptoms during the 14 days after arriving in Canada.

With the ability to capture information requirements electronically, the Government of Canada is also aiming to expand its collection of contact information to those travellers who enter Canada for the purpose of performing an essential job or function. The use of ArriveCAN will help the Government of Canada communicate with travellers via push notifications, and for those travellers required to quarantine or isolate, to promote and verify their compliance with requirements under the Quarantine Act and to record any voluntary report of symptoms of COVID-19 during their 14-day quarantine period.

The ArriveCAN app is available for free on Google Play and Apple App stores.

New Workplace Harassment and Violence Prevention Regulations for Federal Workplaces print this article

To support the prevention of harassment and violence in federally regulated industries and work places, the Government of Canada published in June the Work Place Harassment and Violence Prevention Regulations in Part II of the Canada Gazette. The Regulations will come into force, along with other amendments from Bill C-65, on January 1, 2021.

Employer Obligations

The Regulations outline the essential elements of a work place harassment and violence prevention policy, as well as the procedures that must be in place to respond to occurrences of harassment and violence. These elements include:

  • timeframes for resolution to better support the complainant and alleged individual
  • confidentiality of all parties involved, including witnesses, throughout the investigation
  • protection for employees victimized by a third party (for example, an employee harassed by a client)
  • the qualifications of a competent person to investigate and provide recommendations
  • employer obligations to implement corrective measures in response to the investigation report of a competent person
  • clearly outlining the existing and new roles of the workplace committee
  • support to be provided for employees who have experienced work place harassment and violence

Bill C-65 legislation puts into place a comprehensive approach that takes the full spectrum of harassment and violence into consideration. The framework requires employers to prevent occurrences of harassment and violence, respond effectively to these occurrences if and when they do occur, and support affected employees.

These regulations are intended to support federal employers in their efforts to ensure comprehensive policies and procedures are in place in before January 1, 2021 when the legislation comes into effect.

The Government worked closely with Canadians and stakeholders—including employers and employees, unions, and health and safety representatives in federally regulated industries, as well as subject matter experts, advocacy groups and Indigenous partners—on the Regulations.
