FACTORIES AND INDUSTRIAL UNDERTAKINGS (WORK IN
COMPRESSED AIR) REGULATIONS
(Regulation 32)

ADVISORY LEAFLET FOR ISSUE TO PERSONS WHO WORK
IN OR ENTER COMPRESSED AIR

Read these rules carefully make sure you understand them
for your own sake-follow them

Persons who work in or enter compressed air sometimes get pains in their joint soon after leaving the working chamber. These pains are the "bends", "caisson sickness", or just "pains". They may occur in muscles and other parts of the body. They can almost always be avoided. Pain is sometimes felt in the cars or head during compression. This too can be avoided.

Very rarely a more serious kind of "bends" may occur and a person may even "pass out" suddenly. Immediate recompression is necessary. This is why is so important that you always wear the label you have been given in case you get the "bends" when you are away from the construction site.

A certain number of persons who work in or enter compressed air develop, after a time, small areas of damage in some of their bones. If these affect the hip or shoulder joints arthritis may follow. Failure to obey these rules will increase the risk of bone damage.

YOU MUST NOT WORK IN OR ENTER COMPRESSED AIR UNTIL
YOU HAVE BEEN PASSED AS FIT BY THE DOCTOR

Do not go to work in or enter compressed air if you have a cold in the head, chest infection, sore throat or earache. If you have any of these complaints, you must report to the supervisor in charge of the compressed air operations at the construction site. If you have been off sick through any illness or injury for more than 3 days, you must be re-examined by the appointed medical practitioner before you go back into compressed air.

You must be passed medically fit before you start work in or enter compressed air. If the working pressure is over 14 pounds per square inch, you must be examined by the appointed medical practitioner at least once every 4 weeks. If the working pressure is below 14 pounds per square inch, you must be so examined at least once every 3 months.

The lock attendant has to keep a record of all persons who enter and leave the lock, and also has to control all decompression. Always obey his instructions.

YOU MUST ALWAYS WEAR THE LABEL ISSUED TO YOU

If you get an attack of "bends" get back to the construction site as quickly as you can and report to the medical lock attendant who will arrange for treatment in the medical lock.

You must never drink alcohol in compressed air, and smoking is also forbidden.

If you have not worked in or entered compressed air before you must not enter the lock unless an experienced compressed air worker is with you.

If the rate of compression is not controlled by the lock attendant, the contractor employing you may tell the leading man to take charge of the valves which let in the compressed air. If you feel pain or discomfort, warn the leading man or lock attendant at once, and compression will be stopped. If the pain does not go, pressure will be reduced slowly and you will be let out of the lock.

TO REDUCE THE RISK OF "BENDS" DECOMPRESSION MUST BE CARRIED
OUT STRICTLY ACCORDING TO THE RULES

Decompression is usually in 2 stages, the first quick and the second very slow, though other methods can be allowed under the Regulations.

The lock attendant must control all decompressions. Do not try to interfere with his control. You can get in touch with him by means of the speaking tube, the telephone or the observation window.

Attacks of "bends" usually start within 1 1/2 hours after decompression. If the working pressure is over 40 pounds per square inch you should stay near the medical lock for at least 1 1/2 hours. If it is less than this you should stay near the medical lock for at least an hour.

IN THE INTERESTS OF YOUR HEALTH OBEY THESE RULES
IF YOU DO NOT-YOU MAY BECOME SERIOUSLY ILL

LABOUR DEPARTMENT,
HONG KONG.
