Notes on Inspection and Repair It is the responsibility and obligation of all commercial businesses to enforce safety in the workplace, regulations governing dangerous materials, accident prevention and environ- mental protection at all times.
9 People along with the environment must be protected from adverse effects caused by contact with dangerous materials. The procedures for proper handling, containment and/or disposal of all hazardous materials, including wastewater, must be strictly enforced. Important: A Material Safety Data Sheet must accompany any machine/part and a Safety Conformity Certificate must be completed prior to inspection or repair. Please make a duplicate copy and leave the original in the Operation and Maintenance manual. Where special safety precautions are necessary, in addition to careful emptying and clean- ing of the machinery, the necessary information must be given. Inspection or repair of machinery containing radioactive medium will only be performed by authorized personnel under protection and supervision of the owner. The Safety Conformity Certificate is part of the inspection/repair service. We reserve the right to refuse acceptance of this order/service for other reasons.
