All lifts shall be carried out on a platform not less than 2.46m x 2.46m (8ft x 8ft) and secure enough to insure the safety of the lifter, spotters, and loaders. The surface of the platform must be firm, nonslip, and level with no discernible seams in the vicinity of the general lifting area. Rubber mats or similar sheeting materials are permitted. No one is allowed on the platform during lifting sessions except the lifter, the designated spotters, the three referees on duty, and other meet officials as designated if the need arises. Any cleaning, mopping, brushing, or adjusting of the platform, or equipment will be handled solely by these personnel.¬† In addition to the lifting platform a winners platform is mandatory for all World Championships.
2. Bars and Discs
For all powerlifting competitions under the rules of the WPC, only disc barbells are permitted. Only bars and discs that meet all specifications may be used throughout the entire competition and for all lifts. The use of bars or discs that do not conform to specifications will invalidate any records that may have been accomplished. Different bars suited to particular lifts may be utilized providing that they conform to the specifications.

i) ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† Total over all length not to exceed 2.4m, except for specialized squat bar and ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† deadlift bar.
ii)¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† Distance between the inside collar is not to exceed 1.32m or be less than 1.31m except for specialized squat bar.
iii)¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† Diameter of the bar is not to exceed 29mm or be less than 28mm, except for specialized squat bar.
iv) ¬†¬†¬†¬†¬†¬†¬†¬†¬† Weight of the bar and collars is to be 25kg.

viii) ¬† A 15kg bar is acceptable in the raw division for women and lighter weight classes.
b. ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† Discs shall conform as follows:
i) ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† All discs used in competition must weigh within .25% of their correct face value.
ii) ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† The hole size in the middle of the disc shall be such that the disc fits on the bar without excessive play.

vii) ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† The diameter of the largest disc shall be no more than 45cm.
viii) ¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬† It is suggested that discs conform to the following color coding: 10kg and below – any color; 15kg – yellow; 20kg – blue; 25kg – red; 45kg – gold; 50kg- green.

3. ¬†¬†¬†Squat Racks
a) Squat racks shall be of a sturdy construction and provide maximum stability.
The base shall be of such design that it does not impede the lifter or the loaders/spotters. An adjustable rack with a hydraulic mechanism or a non conventional squat rack must be used. It must consist of a one piece designed to hold the bar in a horizontal position.
b) The design of the squat rack shall allow adjustments that accommodate all lifters.
c) Height adjustments should be at incremental stages not exceeding 5cm.
d) For extra safety all hydraulic racks should be capable of being secured at the required height by means of pins.
The bench shall be of sturdy construction for maximum stability and conform to the following dimensions:
a) Length – not less than 1.22mm and shall be flat and level.
b) Width – 29-32cm
c) Height – 42-45cm measured from the floor to the top of the padded surface
of the bench without being depressed or compacted.
d) The height of the uprights on adjustable benches should be from a minimum of 82cm to a maximum of 100cm measured from the floor to the bar rest position. On nonadjustable benches the height of the uprights must be between 87cm and 100cm from the floor to the bar rest position.
e) The minimum width between the insides of the bar rests shall be 1.10m.
f) Adjustable safety racks are approved.
A system of lights shall be provided whereby the referees make known their decisions. Each referee will control a white and a red light, representing a ‚Äúgood lift‚ÄĚ or ‚Äúno lift‚ÄĚ respectively.

It is preferable that the lights be arranged horizontally corresponding with the positions of the three referees. For emergency purposes, i.e. a breakdown in the electrical system, the referees should also be provided with small white and red flags with which to make known their decisions, or using thumbs up or down.
