(a) send a report to the government of the State whose flag the ship is entitled to fly, and a copy of that report to the Director General of the International Labour Office ; and
The International Labour Office is the permanent secretariat of the International Labour Organisation, which is an agency of the United Nations.
(b) where conditions on board are clearly hazardous to health and safety, take such measures as are necessary to ensure those conditions are rectified.
3 A ship to which paragraph (2)(b) applies is liable to be detained until a surveyor of ships is satisfied that those conditions are rectified.
4 A surveyor of ships may permit a ship which is liable to be detained under paragraph (3) to proceed to sea for the purpose of proceeding to the nearest appropriate repair yard.
5 If any of the measures specified in paragraph (2)(b) or (3) are taken, the surveyor of ships must immediately notify the nearest maritime, consular or diplomatic representative of the State whose flag the ship is entitled to fly.
6 A ship must not, in the exercise of the power under this regulation, be delayed or detained unreasonably.
7 In paragraph (1)—
“relevant inspector” means a person mentioned in paragraph (a), (b) or (c) of section 258(1) of the Act (powers to inspect ships and their equipment, etc) .

These sections provide powers to inspect ships and their equipment, powers of inspectors in relation to premises and ships, for the service of improvement and prohibition notices and their reference to arbitration, compensation for invalid prohibition notices and offences.

16 Enforcement of detention
1 Section 284 of the Act (enforcing detention of ship) applies where a ship is liable to be detained under these Regulations as if—
(a) references to detention of a ship under the Act were references to detention of the ship in question under these Regulations; and
(b) subsection (7) were omitted.
Section 284 was amended by the Merchant Shipping and Maritime Security Act 1997, Schedule 1, paragraph 5.
2 Where a ship is liable to be detained under these Regulations the person detaining the ship must serve on the master of the ship a detention notice which—
(a) states that a surveyor of ships is of the opinion that in relation to that ship there is a failure to comply with the requirements of these Regulations;
(b) specifies the matters which, in the opinion of the surveyor of ships, have the effect that in relation to that ship those requirements are not met; and
(c) requires the terms of the notice to be complied with until the ship is released by any person mentioned in section 284(1) of the Act.

17 Right of appeal and compensation
Regulations 14, 15 and 16 (right of appeal and compensation, arbitration and compensation for unjustified detention) of the Merchant Shipping (Port State Control) Regulations 2011 apply to a detention notice served under these Regulations as they apply to a detention order under those Regulations.

THE SCHEDULE
Regulations 2, 5, 6, 7 and 20.

PART 1 Introduction to Parts 2 and 3
1 In this schedule—
“contact current (IC)” is the current created when a person comes into contact with an object in an electromagnetic field, expressed in ampères (A);
“external electric field strength (E)” is a vector quantity corresponding to the force exerted on a charged particle in the environment, irrespective of its motion in space, expressed in volts per metre (Vm-1);
“internal electric field strength (E)” is a vector quantity corresponding to the force exerted on a charged particle inside the human body, irrespective of its motion in space, expressed in volts per metre (Vm-1);
“limb current (IL)” is the current induced in the limbs of a person exposed to electromagnetic fields in the frequency range from 10 MHz to 110 MHz, expressed in ampères (A);
“magnetic flux density (B)” is a vector quantity resulting in a force that acts on moving charges, expressed in tesla (T);
“power density (S)” is the radiant power incident perpendicular to a surface, divided by the area of the surface, expressed in watts per square metre (Wm–2);
“specific energy absorption (SA)” is the energy absorbed per unit mass of biological tissue, expressed in joules per kilogram (Jkg–1); and
“specific energy absorption rate (SAR)” is the rate at which energy is absorbed per unit mass of body tissue, expressed in watts per kilogram (Wkg–1).
2 The ALs and ELVs set out in tables are grouped according to their potential effects, being—
(a) thermal effects, related to the heating of tissue due to its absorption of electromagnetic fields; and
(b) non-thermal effects, related to the stimulation of muscles, nerves or sensory organs due to the presence of electromagnetic fields.
3 The low ALs in Table AL1 in Part 2, and the ALs in Part 3, specify the electromagnetic field levels above which specific indirect effects may occur.
4 The remaining ALs in Part 2 are defined physical quantities related to the direct biophysical effects of exposure to electromagnetic fields. Employers may, as part of their exposure assessment, assess electromagnetic field levels against these ALs. Each AL table states which ELV or ELVs will be complied with if electromagnetic field levels at a particular frequency do not exceed the specified AL. Exposure to electromagnetic field levels that exceeds an AL may still be below the relevant ELV, but in order to determine this the employer will need to undertake a further assessment under regulation 6.
5 Except where otherwise indicated—
(a) “f” is the frequency expressed in hertz;
(b) the ALs and ELVs relate to exposure in any part of the body; and
(c) notes to the tables apply only to the table under which they appear.
6 The applicable safety measures referred to in regulation 5(2) are those required by the notes to the table or tables containing the sensory effect ELV which is to be exceeded, being the note to Table ELV1, and note 2 to Tables ELV3 and ELV5.

1 Between the Low and High ALs, exposure will be below the ELVs but spark discharges may occur. These can be prevented through the provision of information and training under regulation 19 and the use of suitable technical and personal protection measures.
2 The ALs in Tables AL1 and AL2 are root mean square (RMS) values of the field strength. These RMS values are equal to the peak values divided by √2 for sinusoidal fields. The corresponding ELVs in Tables ELV2 and ELV3 are peak values in time, which are equal to the RMS values multiplied by √2 for sinusoidal fields. In the case of non-sinusoidal fields, the exposure assessment under regulation 6 must be based on the weighted peak method (filtering in time domain) or on a scientifically proven and validated exposure evaluation procedure which produces comparable results to the weighted peak method.
3 The ALs represent the maximum field values at any place where a worker may be working, before the entry of any person into the field. In the case of an electromagnetic field source in the immediate vicinity of the body, compliance with the ELVs must be determined dosimetrically on a case by case basis.

(This note is not part of the Regulations)
In relation to workers on United Kingdom ships, and other ships while in United Kingdom waters, these Regulations implement Directive 2013/35/EU of 26th June 2013 on the minimum health and safety requirements regarding the exposure of workers to risks arising from physical agents (electromagnetic fields) (20th individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC) and repealing Directive 2004/40/EC. This Directive has been implemented in respect of other workers by the Control of Electromagnetic Fields at Work Regulations 2016 .
OJ L 179, 29.6.2013, p.1.
OJ L 183, 29.6.1989, p.1.
OJ L 159, 30.4.2004, p.1.
S.I. 2016/588.
The Regulations apply to United Kingdom ships as defined in regulation 2, and, as respects regulations 4, 14 and 16 only, to other ships while in United Kingdom waters. They apply to activities in which workers on ships are, or are likely to be, exposed to risks arising from exposure to electromagnetic fields (regulation 5) and apply exposure limit values. They impose obligations on employers and other persons who have control of matters to which the Regulations relate (regulations 6 to 10 and 18 to 21).
The Regulations require employers to carry out an assessment of the potential exposure of workers to electromagnetic fields (regulation 6) and the risks arising out of such exposure (regulation 9), unless prior to these Regulations coming into force the employer had already made an assessment that would have complied with the requirements for such assessments. Employers are required to make and implement an action plan to ensure workers are not exposed to electromagnetic field levels in excess of the exposure limit values (regulation 8). Employers are required to ensure, as far as reasonably practicable, that any risks identified are eliminated or reduced to a minimum (regulation 10). Employers are also required to provide workers with relevant information and training (regulation 19). Employers are required to ensure health surveillance and medical examinations are provided as appropriate (Regulation 20). There are provisions for enforcement (regulations 11 to 17) and a provision prohibiting the levying of a charge on a worker for anything done under the Regulations (regulation 18). The duties of employers under these Regulations are extended to other persons who have control of the matter (Regulation 22). The Secretary of State may exempt employers from having to comply with the exposure limit values in respect of one or more work activities, providing the exemption is limited in time and subject to prescribed safety conditions (Regulation 23). The provisions of these Regulations are extended to seafarers (Regulation 24). The Secretary of State must review the operation and effect of the Regulations and publish a report within 5 years after they come into force and every five years after that. Following a review, it will fall to the Secretary of State to consider whether the Regulations should continue in force with or without amendment. A further instrument would be needed to revoke the Regulations (Regulation 25).
An impact assessment of the effect of these Regulations on the cost to business has been prepared and copies can be obtained from the Maritime and Coastguard Agency, Spring Place, 105 Commercial Road, Southampton, SO15 1EG. A copy of the Transposition Note is also available from the Maritime and Coastguard Agency.
