Legislation on Hyperbaric Atmospheres

 

In Italy, hyperbaric risk is to be assessed referring to Article 181 of Legislative Decree 81/08.


 

Article 181 - Risk Assessment

1. Within the scope of the assessment referred to in Article 28, the employer shall evaluate all risks arising from exposure to physical agents in order to identify and apply appropriate health and safety measures with special consideration for the standards of Good Engineering Practice.

Appropriate methods for assessment and prevention, as is assessed for microclimate, should be set out for each specific working condition, with reference to the standards of Good Engineering Practice and to existing regulations. 


 

Legislation (Italy)


 

Decree Law 24 January 2012. “Urgent measures on competition, infrastructure development and competitiveness”, also known as the “deregulation decree”.

The foregoing decree refers to the UNI 11366: 2010 standard, “Health and Safety in Underwater and Hyperbaric Professional Activities – Operating procedures, the Italian National Standards Body, Milan, 2010”.

Point 2, of Article 16, cited above, states that the activities “referred to in Article 53 of Presidential Decree No. 886 of 24 May 1979 shall be undertaken pursuant to current applicable regulations and the standards of Good Engineering Practice referred to in the UNI 11366 Standard. Therefore, the reference gives the standard binding value.

The reference to Presidential Decree No. 886 of 1979 is mandatory: in fact, Article 53 concerns the general provisions on the employment of divers, that is to say, on the performance of work underwater for positioning platforms, inspection and maintenance of submerged equipment or for similar work. Article 53 also states that these activities are to be undertaken only by experienced and physically fit personnel, directed by a person with proven competence, in compliance with specific regulations and the standards of Good Engineering Practice.
The reference to UNI 11366 in Decree Law 24 January 2012 defines a national legislative and regulatory framework capable of promoting professional underwater activities under the banner of the highest safety standards for all operators in the sector.
