Grain elevators are considered “elevating devices” covered by Part IV of the CCOHS Regs. (which I’ve attached in its entirety below). As you can see, elevators must:

• Meet CSA Standard CAN3-B44-M85, Safety Code for Elevators, other than clause 9.1.4 thereof, the English version of which is dated November 1985 and the French version of which is dated March 1986;
• Not be used to carry loads over their excess capacity or when a safety device–which would include a self-closing device–isn’t operational*
• You can’t alter, interfere with or render inoperable a safety device*
• Elevator and safety device must be inspected and tested by a qualified person to verify compliance with above: i. before elev/device placed into service; ii. after alterations; and iii. once every 12 months
• Inspections/Tests must be documented, signed by qualified person, list date and location of elev/device inspected or tested and set out person’s findings
• Inspex/Test records must be kept in place where elev/device is located for 2 years
• Elevs/Devices must also be maintained and repaired by qualified person

*Subject to exceptions for servicing, inspection by qualified person
One other small thing: Grain elevators are exempt from Emergency Lighting rules under Sec. 6.10 because handheld lamps are used as the means of emergency lighting in elevators.

As you note, Sec. 2.2(1)-(2) says general means of egress/ingress must be designed and constructed in accordance with National Building Code standards–Problem is that NBC isn’t a govt regulation but a voluntary standard published by the National Research Council and I don’t have access to the darned thing.

Hope this helps.
