Permit T o W ork (PTW)

1. Permit To Work (PTW) D Marock

2. Content Overview Purpose and scope Procedure Record Keeping Example of the PTW

3. Overview What is a PTW? Stands for Permit to Work Written system to control hazardous work Means of communication between parties Identifies individuals with authority & responsibility Considering all the hazards & risks during planning before work commence PTW authorize specific work & ensures that it is carried out by specific people & identifies precautions to be considered during the work

4. Overview When is a PTW needed? Non-routine work which may adversely affect peoples’ health or the environment 2/more individuals/contractors need to co-ordinate activities to ensure work is done safely Activities that require a PTW Hot Work Confined Space Entry Elevated Work (>1.8m) Electrical Work Working with hazardous chemicals Excavations (below ½ m) Asbestos Any high risk job

5. Overview Wasteman requires a Wasteman PTW to be issued for all listed work even if the client issued a PTW Normal day to day Vehicle workshop activities are excluded from the PTW system & workshops will be demarcated as Hot Work areas that do not require PTW (Refer SOP – 11-07-01 SHEQ 30)

6. Purpose and Scope Purpose To ensure that PTW system is implemented, amended & maintained as required by OSH Act Scope All Wasteman sites must have a PTW system in place; this document is applicable to all Site Managers & SHEQ employees

7. Procedure Responsibility Higher Authority (HA) (typically an engineer) certain work needs approval from HA; thus the one may supersede the other approved on the PTW. HA will ensure: • All hazards have been identified by Issuers • Acceptors understand work method & nature • Necessary precautions have been implemented • Examine the site before PTW is signed

8. Procedure Responsibility PTW Issuer(person who will issue the permit for work to be done e.g. workshop manager/expert in the field of proposed work)……will ensure the following before work commence: • Nature and method of work is fully understood • All hazards are identified • Precautions have been implemented • Inform those that may be affected by work • Examine site before signing PTW • Be available on site at all times • Sign off PTW at end of the shift

9. Procedure Responsibility PTW Acceptor (the person/supervisor who manages and supervises the work)…will ensure • Application of issued PTW is under constant supervision • Instruction is taken from PTW Issuer and HA • Instruction is given to those working under PTW • Supervision of work is maintained at all times • Precautions are maintained as stipulated in PTW • Work stops if conditions/methods change –reports to Issuer • Persons/s remain within PTW limits • That PTW is signed off at end of shift

10. Procedure Responsibility Employees (workers performing the job to be done – this can be WM employees. When Contractors perform a job under a WM permit, they are also seen as Employees under the permit conditions) • Sign PTW once Acceptor/Supervisor explains conditions • Work under the PTW conditions • Stop work & report to Acceptor if conditions change • Sign off the PTW at the end of shift

11. Procedure Training Requirements • Acceptors must be trained in 1 day course on PTW • Issuers & Higher Authority attend a 2 day PTW course • Ensure all standby employees/contractors are trained for the jobs they perform e.g. first aid for confined space enrty – level 3 Permit Validity Period • PTW valid for one shift – signed off @ end of shift • A PTW can become invalid during a shift due to: Change in conditions – STOP & report immediately to Issuer Emergencies– STOP & report immediately to Issuer

12. Procedure Verification PTW system will be audited as part of all internal & external audits. A ‘live’ PTW can be audited if the Auditor is on site @ the time the PTW work is carried out. Document control PTW will be printed by SRT SHEQ officer. Printer will ensure: • PTW is printed on A3 in triplicate – last copy remain in PTW book – one copy to acceptor, other is kept in PTW station. • Continuous atmospheric analyses to be recorded on the back for all confined space work • A PTW nr is issued in sequence & printed in sequence

13. Procedure Document control SHEQ Department’s responsibility: • Implement the SOP • Order the books • Ensure sequential control • Maintain records • Audit the use of the PTW • Arrange training • Implement the station • Be part of the issuing & accepting of the PTW

14. Procedure PTW Stations Specific area on the site where all PTW’s are issued, lockout devices are controlled and all ‘live’ PTW’s are kept until signed off. Station must be accessible but controlled.

15. Procedure • Insert applicable names – Responsibilities clear. • PTW 1-4: space for live PTW–anybody on site can determine what work is done under PTW conditions. • PTW documentation – SOP’s & actual PTW book & lockout tags are available at station. • Lockout section = The first lockout device (LO-D) – lock still in place = The lockout device is used, removed & signed out. If LO-D is issued with tag & PTW, person doing LO sign it out & note PTW nr on the board (wipe out type board – cleaned after device return) • Notice board – Summary notes on PTW

16. Procedure How to complete the PTW • If the specification is required  (circle) the block. • If the specification is not required/applicable strike it through and note N/A over it. • All sections must be completed with either a /N/A – blank areas cause confusion. • Section called “Type of permit” can be completed by only  in either the Yes/No block. • The PTW must be signed off before the workers leave and handed back to the Issuer immediately.

17. Procedure Hot Work (Welding, flame cutting, grinding...) • Certified competent person operate equipment • Wear appropriate PPE • Leads and electrodes must be insulated • Partition off work area with “unauthorized persons prohibited” signage; • Confined space work to be ventilated • Work not to be performed in wet/damp places unless compliant to General Safety Regulation (GSR) Section 9(3)(1,b,c,d) • Flashback arrestors must be fitted to welding equipment

18. Procedure Hot Work (Welding, flame cutting...) cont. • No permit given for hot work in closed vessels or where ignition/explosion/poisonous substances may occur • Proper and adequate fire precautions must be in place – competent persons to operate equipment should be available at all times during work. • Metal type should be identified before cutting, welding or soldering – precautions to be taken

19. Procedure Confined Space Entry (refer GSR 5) • Competent person check air quality before entry • Area to be properly ventilated & all incoming pipes, ducts/openings locked out with chains & locks • Where sub-regulations 2(a) can’t be met; person entering to wear breathing apparatus, continual air quality monitoring and must be attached to lifeline • Qualified first aider must act as safety attendant and must have approved resuscitation equipment • Notify medical centre/emergency response team of any confined space entry work • Continuous atmospheric meter readings must be recorded

20. Procedure Elevated Work (refer GSR 6) • No permit given to work in elevated positions, unless such work is performed safely from a ladder/scaffolding. • Scaffold Erector & Supervisor must be trained and appointed • Ladders / scaffolds must be properly secured before work • Relevant harness & safety belt to be issued and worn • Roof ladders, duck-/crawling boards made secure • All work above 1.8m to be conducted under PTW. • Medically fit to work above 1.8m – Legislation! • Fall protection plan – use the Working at Heights SOP • Structural integrity might be required before work commence
