Having a gas detection system in place ensures that the ventilation system operates when the gas concentration level is at a dangerous level. These fumes have been linked to a number of health related issues and are a concern for the provincial health and safety boards. At high exposure levels, they can result in death. High concentrations of these fumes are extremely dangerous. Being in an indoor environment, the ventilation system does not know that these gases are present therefore, cannot being diluted and / or vented outside the building. The exhaust is venting toxic gases, such as carbon monoxide, propane, and nitrogen dioxide, from the rear of the machine. The health and safety of individuals working near or around equipment, such as propane powered forklifts, are at risk. Such gases include (but not limited to) carbon monoxide, carbon dioxide, oxygen, nitric oxide, nitrogen dioxide, and hydrogen sulphide. Gases that have density close to that of air should be installed in the breathing zone, aka respiratory zone, which is 4-6 ft from the floor. Gases that are lighter than air should be installed on or near the ceiling, include (but not limited to) ammonia, methane, and hydrogen. Such gases include (but not limited to) carbon dioxide, chlorine, ozone, propane, and refrigerants. Gases that are heavier than air should be installed 6” from the floor. The focus, of course, is on what this area contains in terms of toxins and gases and how this area can be accurately tested for safety reasons. (B) For the determination of the exposure of each employee a sufficient number of samples shall be taken to characterize the employee's exposure during each work shift. In just 5 minutes you can start to enjoy the deep relaxation and other health benefits of slower therapeutic breathing.Breathing. (A) In all personal monitoring, samples representative of the exposure in the breathing zone of the employee shall be collected.
This is “ 72” above the floor” (ASHRAE Standard…). Breathing Zone is a simple and effective guided breathing exercise. The breathing or respiratory zone is defined as “the area from which the employee draws air and has been defined as being as close as possible to the nose and mouth and a hemisphere forward of the shoulders with a radius of 6 to 9 inches” (Review of ANSI/ASHRAE Standard 62.1-2004…). It states that “dusts, gases, fumes, vapours and mists found in the workplace environment shall be measured in the respiratory zone of workers or, if this proves to be impossible owing to the lack of equipment for taking sampling in this zone, then outside the breathing zone but in a place located as close as possible to such zone” (Division V: Air Quality: 44 Methods). Recently, Quebec’s regulation has reinforced CETCI’s recommendations. (CETCI) has always recommended that they be installed in the breathing zone. In contrary, Critical Environment Technologies Canada Inc. In the past, vehicle exhaust gas detectors have been installed on or near the ceiling.
