1 PED Hazard Analysis Practical guidance
by: ing. H. Verschuren Lloyd’s Register Netherlands

2 Content Hazard Analysis Essential Safety Requirements
Instructions for use Hazard analysis, example

3 Manufacturer Responsibilities ensure design and manufacturing to ESR’s
ensure conformity assessment with ESR’s

4 Hazard Analysis Consider all applicable hazards. Known and foreseeable, use and foreseeable misuse. Take into account all ESR’s if applicable. Instructions for use, containing all safety information.

5 Hazard Analysis Method EN 1050 elimination reduction warning

6 Essential Safety Requirements
From cat I to IV obliged manufacturer has to provide a description of solutions adopted to meet the ESR’s. If no is harmonised standards are used.

7 Instructions for use Pressure equipment should be accompanied by instructions for use. Contain information relating to: mounting / assembling putting into service use maintenance

8 Instructions for use Content
All info as mentioned in ann I §3.3 “Marking and labelling” All other relevant safety info All hazards not prevented by design or protective measures

9 Hazard Analysis evaluation of all appl hazards
description of solutions adopted to meet ESR’s (harm standards not used) Determining content for instructions for use

10 Hazard Analysis example
Type of hazard 2.2 design for adequate strength Internal pressure

11 - normal operating conditions - regeneration conditions
Type of hazard Rele-vant Y / N Risk estimation by Description of hazard 1 Internal pressure - normal operating conditions - regeneration conditions - thermal liquid expansion - exothermal reactions/run away Y N M 2 External pressure - vacuum - condensing steam/vapour due to cooling down

12 Description of hazard Risk No. Action Required Y / N Inlet from V1504, heating from steam jacket

13 Description of hazard Risk No. Action Required Y / N Inlet from V1504, heating from steam jacket 72

14 Description of hazard Risk No. Action Required Y / N Inlet from V1504, heating from steam jacket 72 Y

15 If applicable: risk reduction by Additional precautions
Design Use 3) Construction Reduction Additional precautions Warning EN NA Y
