Compressed Air Work

In Hong Kong the compressed air works are governed by the Factories and Industrial Undertakings (Work in Compressed Air) Cap 59M Regulations. Under this regulation, it is mandatory for contractors and tunneling companies to appoint a medical practitioner to supervise all medical matters which may arise in connection with the construction work.
