and Commissioning Of 33kv Earthing Transformer at PMU Pulau Indah.
2. SCOPE OF METHOD STATEMENT
The scope of method statement (under TNB Grid) covers for disassembly of 33kV Earthing
Transformer Installation Testing and Commissioning.
3. WORK PROCEDURE
3.1.
Preliminary Work
3.1.1.
a.
Standard Operation Procedure (SOP) for Covid-19
World Health Organization states that the Covid-19 virus affects different people in
different ways. The WHO states that the common symptoms include:
i. Fever
ii. Tiredness
iii. Dry cough
Other symptoms can include:
i. Shortness of breath
ii. Aches and pains
iii. Sore throat
iv. And, in a few cases, people may report diarrhea, nausea or a runny
nose
It is believed that up to 30% of those infected do not show any symptoms and so
cleanliness and social distancing must be maintained.

`
Reference: National Security Council (NSC), Ministry of Health (MOH) (Covid 19:
Management Guidelines for workplaces), CIDB (Guidelines of Covid 19
Prevention Practices at Construction Site), Occupational Safety & Health Act 1994.
b.
The following advice is derived from general advice provided by the WHO. Basic
protective measures against COVID-19 as below:
i.
