Starting up the Oven Safely
A safe installation includes a proper startup of the oven prior to allowing operation. Only qualified personnel should conduct the startup procedure for the oven. Qualified personnel include trained maintenance personnel or electricians. Unless specifically trained, oven operators do not usually qualify to start up the oven. Only qualified personnel should enter the control cabinet due to the high voltage involved. Detailed startup procedures are addressed in a separate section of this manual.

Operating the Oven Safely
The predominant causes of fires, explosions and personal injury related to industrial ovens are improper use. Inadequate training, lack of maintenance and poor housekeeping. The operator must take an active role in assuring that the workplace is safe. Operators should be thoroughly trained prior to their use of the oven. Their training should include operating instructions and review of the safety issues that immediately follow. Operating instructions are addressed in a separate section of this manual.
1.1
Maximum Solvent Content
This oven is designed to handle a limited amount of solvent per batch. Solvent levels in excess of the maximum allowed may create an explosive atmosphere in the oven. Operators should contact their managers if they do not know what portion of their load is solvent.
1.2
Paper, Wood and other Solid Combustibles
Do not load paper, wood or other solid combustibles without consulting Col- Met Spray Booths, Inc. for appropriate safety measures that must be taken for these processes. There is a danger of fires and explosions resulting in property damage, personal injury or death.
1.3
Maintenance – Periodic and On-demand
The operator has an important role in the proper maintenance of the oven. The operator should shut down the oven and immediately notify management if the odor of gas is present. The operator should immediately notify their supervisor of any changes in operating performance. The operator should NOT restart the oven if a high limit alarm exists. The operator should notify management and insure that the cause of the high limit trip is corrected before the oven is restarted.
1.4
Proper Housekeeping
In maintaining safe oven operation, it is important that proper housekeeping be performed at all times. Allowing varnish to build up in handling carts, for example, contributes to the maximum allowable solvent in the oven and could subsequently cause a fire or explosion. All drippings and combustible products should be cleaned regularly from handling carts and the oven interior. Certain applications cause flammable materials to accumulate in oven exhaust ducts. These items should be inspected and either cleaned or replaced as necessary.
