Hoses , especially , must be checked carefully before each use , and should be replaced if there are bulges , cracks , cuts , soft spots , or blisters .
Tanks should not be filled to more than 85 percent of capacity , as increasing outside temperatures cause the liquid to expand and the vapor pressure in the tank could rise to a potentially dangerous level , leading to a possible rupture or explosion .
A break-away coupler in the ammonia line that runs to a tool bar is a recommended safety precaution to provide protection if the equipment separates accidentally .
When towing a nurse tank , drive at speeds of 25 mph or slower . In Minnesota , anhydrous ammonia tanks must
be equipped with two red reflectors at the extreme left and right rear sides of the end of the wagon . The widest portion of the towing vehicle and wagon combination must also display a red or amber light at the extreme left end of the combination visible from the rear and an amber or white light visible from the front .
If skin is exposed to anhydrous ammonia , flush the exposed area with clean water for at least 15 minutes . Remove contaminated clothing . Do not apply salves , creams , or ointments , which may seal residual ammonia in the skin and cause further damage .
Eyes should also be flushed for 15 minutes or more if ammonia enters them .
Doctors should be contacted immediately after administering emergency first aid . If ammonia is inhaled in high concentrations , cardiopulmonary resuscitation may be required .
If ammonia is swallowed , contact a doctor immediately . If possible , drink large amount of water to dilute the chemical . Vomiting should not be induced if a victim is in shock or unconscious . If vomiting occurs , keep the head lower than the hips to prevent vomit from entering the lungs .
