Occupational Health and Safety Act, 1993 (Act No. 85 of 1993)Guidance NotesPressure Equipment Regulations, 2009Regulation 10 - Pressure and Safety Accessories |
| (1) | No user may require or permit pressure equipment to be used unless it is provided with all the pressure and safety accessories required by the relevant health and safety standard which is incorporated into these Regulations under section 44 of the Act and used in the design, construction and manufacture of such pressure equipment: Provided that alternative safety accessories other than those required by the standard may be fitted with the written approval of an approved inspection authority. |
| (2) | In the absence of a requirement referred to in subregulations (1) in the relevant health and safety standard which is incorporated into these Regulations under section 44 of the Act and used in the design, construction and manufacture of such pressure equipment, safety accessories shall be provided by the user as required by the approved inspection authority and those safety accessories shall be so selected, arranged and installed as to be safe for the particular purpose for which the pressure equipment is to be used. |
| (3) | Every user of a steam generator or pressure vessel shall ensure that the steam generator or pressure vessel in use is fitted with at least one pressure measuring device. |
| (4) | Every user of a steam generator or pressure vessel shall ensure that the steam generator or pressure vessel in use is fitted with at least one safety valve and that safety valve is kept locked, sealed or otherwise rendered inaccessible to any unauthorized person. |
| (5) | The number and capacity of the safety valve referred to in subregulations (4) shall comply with the requirements of the design standard for the steam generator or pressure vessel or as required in terms of sub regulations (2). |
| (6) | Every user shall ensure that the automatic controls and indicators of a steam generator, pressure vessel or piping are arranged, installed, maintained and operated in accordance with the relevant health and safety standard which is incorporated into these Regulations under section 44 of the Act and used in the design and manufacture of the steam generator, pressure vessel or pressurized system: Provided that in the absence of such provisions, where automatic controls and indicators are installed, they shall be selected, arranged and installed subject to the written approval of an approved inspection authority. |
Notes:
| (a) | PER 10(1) allows the user to use system protection where the health and safety standard allows it and regulation 10(4) is superfluous. |
| (b) | Pressure indicating device does not need to be located directly on the equipment but may be remotely displayed for example on distributed control systems. |
| (c) | The pressure measuring device shall be located such that it is representative of the highest pressure in the system. It shall not be possible to isolate any of the equipment with the pressure measuring device from other equipment relying on that pressure measuring device in the system while in operation. The intent is to have control over the pressure in the pressure equipment. |
| (d) | Pressure and safety accessories on steam generators or pressure vessels may be installed according to the PER at the time of commissioning of the equipment. For example pressure equipment regulated under the previous regulations can have system protection as allowed by the PER. |
| (e) | Safety accessories for ASME pressure equipment will be certified by either ASME or a European Category IV Conformity Assessment |
| (f) | Safety accessories protecting non pressure equipment as excluded in PER 2.(3) shall be conformity assessed in accordance with SANS 347 |
| (g) | The user is responsible to ensure that safety and pressure accessories are installed, maintained and set as per the requirements of the applicable health and safety standard. [See also PER 11 Note (j)] |
| (h) | Pressure accessories shall be classified independently of the pressure equipment to which it is attached |
| (i) | Over pressure protection by means of system design including instrumented safety systems such as high-integrity pressure protection system (HIPPS) may be used instead of pressure relief devices provided that the system is recognised by the relevant health and safety standard which is incorporated into these Regulations under Section 44 of the Act |
