How to determine if your workplace is an MHI

What is MHI

MHI is the short form of “Major Hazard Installation”, in the context of Singapore’s WSH(MHI) Regulation.

MHIs refer to fixed installations, including Petroleum refining and manufacturing facilities, chemical processing plants and facilities where large quantities of toxic and flammable substances are stored and/or used.

MHI classification

A workplace will be classified  as an MHI under the WSH(MHI) Regulations, if it meets both of below two conditions:

  1. its nature of work activities, and
  2. its inventory levels of dangerous substances (present or likely to be present) meeting or exceeding threshold quantities.

For condition 1, the works activities involve processing, manufacturing or having bulk storage by way of trade or for the purpose of gain of any dangerous substances specified in the First Schedule of WSH(MHI) Regulation.

Condition 2, on the quantity of dangerous substances,will be satisfied  if at least one of the below two criteria is met:

2.1 Quantity of the individual dangerous substance present or is likely be present equals or exceeds the prescribed threshold quantities; or

2.2 aggregation of the ratios of dangerous substances for one or more hazard classes(i.e. Physical, Health or other hazards) equals to or exceeds 1.

Preparation for Safety Case Regime Starts now

  • What is Safety Case Regime?
  • Who will be affected?
  • When will it take effective?
  • As an MHI, how should I prepare for it?

…

Your concern list continues.

Every MHI needs to get ready for safety case regime under WSH(MHI) regulations, which will take effective in Sep 2017.

SafetyCase.SG would like to share some of our perspectives about your above concerns.

 

Firstly, you are not alone.

There are about 120 MHIs in Singapore and all of them will need to comply to WSH(MHI) regulations. And the regulation body MHD(Major Hazard department) has been  doing its best in order to guide and support all the MHIs. It’s not the MHI, but also MHD who wants to make Safety Case Regime a success for Singapore.

As it’s a novel concept in Singapore, it’s relatively reasonable to state that Safety Case Regime is a big challenge for all stakeholders in Singapore.

Secondly, SafetyCase.SG will stand behind you for free.

SafetyCase.SG has a heart for Singapore’s safer environment. We’ll help organize regulation news, integrate the  regulations requirements and provide our technical perspectives independently for your reference for free.

Thirdly, there are a lot of safety case consultants available in the market.

QRA, HAZOP, Functional Safety, Explosion protection, Safety Case development,….. Any area you think of, there are professionals/consults available. Only issue is we need to discern their competence. Based on what? Certification? Education? Experience? We’re unable to come out of a short answer, while we can discuss this topic together considering our earlier exposure in safety industry.

Fourthly, capability can be and will be built up.

Training, learning and practice will help build up our capability. It will take our heart, energy, money, time and so on. Years later, Singapore will be full of people with safety case expertise.
