To avoid problems, plan ahead. 

 Before Sealing the Room 



(1) The manhole in the gastight door should be at least 

 24 X 30 inches high to accommodate a large person with breath- 

 ing equipment strapped to his/her back. 



(2) There should be a ladder inside the room, near the 

 refrigeration unit. When loading the room, leave sufficient 

 space to move and use the ladder around the equipment. 



(3) Place a danger sign on each gastight door. "DANGER - 

 OXYGEN TOO LOW FOR PEOPLE TO BREATHE" or other suitable warn- 

 ing should be printed on the sign using letters at least 1-1/2 

 inches high. 



Entering a Sealed CA Room 



If you have a New York State CA registration and need to 

 break the seal before the end of the initial 90 day period, 

 notify the New York Department of Agriculture and Markets in 

 advance. 



If you must go to a place in the CA room where you cannot 

 be EASILY DRAGGED TO THE DOOR, open the room and vent with air 

 until the oxygen is 21% before entering (see item 6 on next 

 page) . 



If you need to enter a sealed CA room (one from which 

 you can be easily drag-rescued) proceed as follows: 



(1) Have at least 2 sets of tested breathing apparatus 

 ready. If you don't own your own equipment, know where 

 functional breathing equipment can be borrowed or rented. 

 The breathing equipment should be fed with air (compressed 

 or fan blown) not pure oxygen. The mask should be held in 

 place with straps. Scuba diving equipment is dangerous to 

 use because the mouthpiece may fall from your mouth if you 

 fall.
