How is that possible? Main duties don't match.
NOC 2263-B: This group also includes the following titles: environmental health officer, hazardous waste inspector, health and safety officer, health standards inspector, occupational health and safety officer, pollution control inspector, public health inspector, restaurant inspector, rodent control inspector, supervisor, public health inspectors, water inspector.
Inspectors in this unit group evaluate and monitor health and safety hazards and develop strategies to control risks in the workplace. They inspect restaurants, public facilities, industrial establishments, municipal water systems and other workplaces to ensure compliance with government regulations regarding sanitation, pollution control, the handling and storage of hazardous substances and workplace safety. They are employed throughout the private and public sectors.
This is far away from 1122 duties, except for those who have ISO certificates, but in that case they have to be employed for outsourcing companies and have other duties which match more than 70%.
I would like to see one example of reference letter from a person who works as OHS or EHS officer, and who applied under NOC 1122!
