8.0 RECOMMENDATIONS

Formaldehyde:

• Implement an exposure control plan as per OHS Reg 5.57 (2) – Designated Substances. This

regulation states that substances designated as ALARA substances must be substituted,

however, if it is not practicable then the employer must implement an exposure control plan

to maintain workers’ exposure as low as reasonably achievable below the applicable

exposure limit.

• It is recommended that the leaking spigot on the formalin container be discussed with the

company representative. The leaking spigot must be maintained in good operating condition

by the department in order to prevent leaks.

Nitrous Oxide:

• Management should continue investigations to reduce peak exposures to below the 5X

excursion limit of 125 ppm.

• Install local exhaust ventilation. Few solutions are presented in the literature as to the type of

local exhaust system that would decrease the peak exposures, however, it is possible that a

slotted hood located at the head of the bed might be an effective solution.

and/or

• Conduct a feasibility study to look at the costs and benefits of increasing the number of room

air changes per hour.
