Dear Khun Arrita/Khun Tom,
As a result of an incident that occurred last Friday whereby a goods lift dropped uncontrollably at Zone 3! As a safety precaution it has been decided to close off the use of all elevators in all buildings at both zones with immediate effect until we obtain reports from an independent engineer on each elevator as to whether they are safe to use or not.
Khun Chi our in house maintenance supervisor is currently contacting an independent company to attend our premises to conduct these surveys and provide us applicable reports/recommendations/quotations relevant to each elevator.
Immediately please erect signs to all elevators as follows:
'Elevator Out Of Action Until Further Notice, Please Use The Stairs, Sorry For Any Inconvenience Caused'
The initial findings into the investigation have identified that the cogs to the elevators camshaft were worn! thus causing it to drop! This defect should have been identified by our current elevator maintenance provider and brought to our attention when undertaking the last inspection, and raises concerns over there competency to provide such services! which unbeknown to the safety department had been an issue raised previously between our in house maintenance department and a member of the purchasing department.
Khun Arrita, please liaise with Khun Sombat over this matter and both of you please ensure that all elevators are isolated.
In closing, I will brief you in person on the contents of this mail to ensure you understand the content and keep you posted on any other developments as soon as I receive any.
