2.3.10 Intoxicants
Diving under the influence/aftereffects of intoxicants can pose serious consequences for the diver’s life and health. Alcohol and other intoxicants must not be consumed less than eight hours before diving. If the diver has taken anaesthetics or stimulants (medicines, etc.) less than 24 hours before diving, he/she is obliged to notify the diving supervisor of this. In such cases, the diving supervisor shall consult with a physician if he/she is in doubt about whether diving may be permitted.

2.6 Safety provisions

2.6.1 General provisions for diving
For all diving, there must be sufficient surface capacity. The diving supervisor must consider the competence of the standby personnel on a case by case basis in relation to the number of divers and the type of diving to be implemented. During all diving, there must be personnel on the surface with the necessary training in line signals, as well as be trained to deal with an emergency situation – particularly in terms of notification, transport and first aid. All dives must be led divers who hold a diving certificate for the type of diving equipment to be used.

As a minimum, diving operations shall be performed by a diving supervisor, a diver and a standby diver.

2.6.2 Diving tables
Recognised diving tables must be used during all diving operations.

2.6.3 Work instructions
The diving manager or the person he/she authorises shall prepare work instructions before the diving is initiated. An approved itinerary/cruise programme including defined distribution of responsibility and framework conditions may be used.
2.6.4 Diving assignment
The diving assignment must be led by a diver certified as a diving supervisor.

2.6.5 Training dives
Training diving shall be performed regularly in order to maintain one’s diving skills. A diving supervisor must be on the surface during all training diving.
2.6.6 Diving in pairs
When diving in pairs, one of the divers must be appointed as the leader of the pair, normally the one with the voice communication line. In such cases, the divers must use a buddy line.

2.6.7 Standby diver
For all diving, the diving supervisor must assess the relevant risk factors against the required state of readiness of the standby diver. The standby diver must have a diving certificate of minimum class S and be certified for the depth to be dived to.
The standby diver must as a minimum be dressed in a diving suit and be advisable. The standby diver must be trained to deal with emergency situations under water and be given the necessary training in emergency procedures for the equipment to be used. The standby diver must be experienced diver.

The standby diver may be one of the divers if separate lines are being used and / or the standby diver’s task is to monitor the other diver.

2.6.8 Diving flag
In order to warn that diving is being performed, a signal flag ALPHA must be used. This must be visible is ready to be displayed at the dive site. When diving in the dark, a red-white-red strobe may be used.

2.6.9 Notification
When diving on or near a vessel, or in areas where there is a danger that other activities may impact on the safety of the diving operation, the necessary notifications must be made before the diving starts. Examples of entities to be notified include the port authorities, vessels in the vicinity and relevant military departments. Notification is also necessary in areas where diving is not permitted, e.g. near fish farms, mines / cables and protected areas. The diving supervisor is responsible for providing notification / obtaining permission prior to diving in the area in question.

2.6.10 Safety boat
The safety boat should be at the dive site and ready for use when appropriate. This must be assessed by the diving supervisor in relation to the planned activity, conditions at the site and the nature of the assignment.

2.6.11 Signal line
The signal line must be properly fixed to the diver. The diver and line attendant must exchange regular line signals, except in circumstances when the diver’s condition is controlled in another manner. If the diver does not respond to a signal, the signal shall be repeated. If the diver fails to respond to that signal too, measures shall be implemented immediately to bring the diver to the surface.

As a general rule, all divers must use a signal line with communication.

2.6.12 Voice communication
Voice communication provides increased monitoring of the diving activity. Consequently, one should strive to utilise this during all types of diving.
In connection with stationary diving assignment, voice communication and video surveillance in real time should be used. In cases where voice communication fails, the dive shall continue using line signals. The diving supervisor shall assess whether the dive shall be interrupted on the basis of the depth and duration of the dive and the possible decompression time. In the event that there is also a risk that the diver can get stuck, the dive must be interrupted.
In connection with surface supplied diving, voice communication shall normally be utilised between the diver and the surface.

2.6.13 Calling the diver to the surface
A suitable acoustic signal may be used to call the diver to the surface in special situations. Examples of such signals are an explosive acoustic signals or mechanical knocking signals. In that event that acoustic signals containing explosives shall be used, the personnel must be given appropriate training in the use, safety clearance distance, transport and storage of this.

2.6.14 Hyperbaric chamber
Diving involves the risk of injuries that require treatment in a hyperbaric chamber. Consequently, in connection with all diving, a plan shall be prepared concerning notification and transport to a manned hyperbaric chamber.

In connection with diving operations with planned decompression stops, the diving supervisor has a particular responsibility to assess risk in relation to the depth, duration and decompression profile of the dive and any other risk factors.

2.6.15 Buoyancy control
In cases where a buoyancy compensator is used for buoyancy control, air from the device shall not be used. However, this air may be used in order to ensure positive buoyancy on the surface after the dive.
If the diver requires heavier weights or weighted dive boots in order to stand steadily, for instance to perform for diver should be able to stand firm, for example to perform sludge removal or other tasks on the seafloor, this must be executed with surface supplied equipment.
In connection with scuba diving / swimming, tools or other equipment should never prevent the diver from ensuring positive buoyancy in an emergency situation.

2.6.16 Exerting diving
After exerting diving, the diver shall not be left alone or attempt to sleep in the first hour after completion of the dive.

2.6.17 Diving with limited access to the surface
Diving with limited access to the surface describes situations in which one has limitations and may not dive more than six metres into or under a system with a scuba compressed air breathing system.

2.6.18 Diving with no access to the surface
Diving with no access to the surface describes situations in which one enters a system that can pose immediate mortal danger without an alternative source of air. In connection with diving with no access to the surface (e.g. diving inside a ship wreck, work in trawls and seine nets or under ice, etc.), the diving supervisor shall ensure that the divers have the necessary competence and training to perform the diving. The diving supervisor must assess the measures that must be implemented in order for the diving to be implemented in a safe manner.

The following supports are mandatory:

- voice communication with surface supplied equipment

- standby diver

2.6.19 Diving in polluted water
In connection with diving in water that is polluted, measures for cleaning should be prepared.

2.6.20 Diving in the dark/poor visibility
Divers must be equipped with two separate suitable light sources, one of which shall only be used in the event of emergency situations. If surface marker buoys are used, these must be visible.

2.6.21 Use of tools under water
In connection with work under water involving tools, the diver must be given the necessary training in the mode of operation, safety rules and risk factors of the tool(s) in question.
2.6.22 Lifting operations
In the event of lifting operations under water, the diver must not move immediately above or below the hanging object. The diver must not use their own valve / inflator to inflate the lifting balloon.

2.6.23 Search operations
When divers are used in search operations, the divers must be given the necessary training in the relevant type of search.
