SCHEDULE Regulations 2, 4, 5, 6 and 11

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);

“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 are set out in tables and 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 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 that AL. Exposure to electromagnetic field levels in excess of the AL may still be below the relevant ELV but the employer will have to undertake further assessment to determine this under regulation 5.

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 4(2) are those required by the notes to the table or tables containing the sensory effect ELV which is to be exceeded, being—

(a) the note to Table ELV1; and
(b) note 2 to Tables ELV3 and ELV5. PART 2

Tables ELV2 and ELV3

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 10 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 5 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 an employee 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, case by case.

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations implement, as respects Great Britain, Directive 2013/35/EU of the European Parliament and of the Council (OJ No L 179, 29.6.2013, p1–21) on the minimum health and safety requirements regarding the exposure of workers to the 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.

These Regulations apply in Great Britain, and outside Great Britain to the extent provided by regulation 14.

Part 2 sets out the main duties placed on employers under the Regulations. Part 3 sets out supplementary duties and gives the Health and Safety Executive (“the Executive”) limited powers to exempt employers from specific duties. The Schedule provides more specific details on how employers are to comply with their duties.

The main duties and provisions in Parts 2 and 3 of these Regulations are as follows—

(a) all employers must ensure that, except in circumstances prescribed by the Regulations or where permitted under an exemption issued by the Executive, employees are not exposed to electromagnetic field levels in excess of prescribed exposure limits (regulation 4(1)). These limits are contained in Part 2 of the Schedule;
