01 / DATA CENTRE SAFETY
Quick answer: data centre PPE should be selected by work zone and task, not by a single site-wide kit. Electrical rooms may require isolation / LOTO, voltage-rated gloves and arc-rated PPE; battery rooms may require chemical splash protection and emergency eyewash; fit-out work can require head, eye, foot, high-visibility and fall protection; mechanical plant areas may add noise, heat, refrigerant or maintenance hazards. Malaysia's 2026 Suruhanjaya Tenaga Electrical Safety Management Plan (ESMP) is an important current electrical-safety framework, while OSHA 1994, DOSH chemical-risk requirements and the facility operator's permit / contractor standards remain relevant to the wider site.
This page is rebuilt as the broad data centre safety and PPE authority page. Haisar's separate Data Centre Maintenance PPE article should stay focused specifically on operational maintenance teams so the two pages do not compete for identical intent.
02 / MALAYSIA FRAMEWORK
There is no single “data centre PPE regulation” that replaces the normal Malaysian safety framework. Data centre projects combine electrical systems, construction / maintenance activities, chemical hazards, lifting / work-at-height tasks and operator-specific access controls.
| Reference | Why it matters |
|---|---|
| OSHA 1994 | General workplace safety duties and risk-assessment foundation. |
| Suruhanjaya Tenaga ESMP 2026 | Current electrical-safety management framework covering risk control, PPE, testing / calibration, management of change and PTW for high-risk electrical work. |
| Electricity Regulations 1994 | Competent-person and electrical-installation responsibilities relevant to electrical work. |
| USECHH / CHRA | Relevant where battery electrolyte, cleaning chemicals, water-treatment chemicals or other chemicals hazardous to health are handled. |
| Operator / principal-contractor rules | Site induction, permits, access, LOTO, ESD control, PPE zones and documentation can be stricter or more specific than the general regulatory baseline. |
Important: PPE is the last layer of the control hierarchy. For electrical work, the 2026 ESMP requires risk assessment and higher-level controls before appropriate PPE is used for the residual risk.
03 / ZONE-BASED SELECTION
| Zone | Main hazards | Selection direction |
|---|---|---|
| MV/LV switchgear, UPS & PDU rooms | Electrical shock, arc flash, stored energy | Isolation / PTW / LOTO first; then voltage-rated and arc-rated PPE matched to the task / assessment. |
| Battery / UPS battery rooms | Electrical energy, electrolyte / chemical splash, gases or thermal events depending on battery chemistry | Chemical eye / face / hand protection, emergency eyewash / shower where assessed, electrical controls and battery-system emergency procedures. |
| Active data halls | Sensitive electronics, ESD-control requirements, raised floors, rack / material handling | Facility ESD controls, task-based eye / foot / hand protection, clear floor-opening controls and access rules. |
| Mechanical plant / cooling areas | Rotating equipment, noise, heat, refrigerants / treatment chemicals | Task-specific eye / hand / hearing / respiratory protection based on the actual maintenance activity and chemical information. |
| Generator / fuel areas | Noise, hot surfaces, mechanical work, fuel / oil exposure, electrical generation | Task-based PPE plus energy isolation, ventilation / monitoring and spill / fire controls as applicable. |
| Construction / fit-out zones | Overhead work, cutting / drilling, temporary electrics, work at height, vehicle movement | Construction PPE, fall protection where required, eye / face protection and electrical controls matched to the work. |
| Loading / external yards | Vehicles, lifting, weather and delivery activity | Hi-vis / traffic controls, safety footwear, lifting-zone controls and weather-appropriate PPE. |
Procurement lesson: “100 sets of data centre PPE” is usually too vague. Build the BOQ by work package / zone: electrical switching, battery maintenance, fit-out, mechanical plant, data-hall operations and external works.
04 / ELECTRICAL SAFETY & LOTO
Suruhanjaya Tenaga's 2026 ESMP requires the licensee to provide appropriate PPE for electrical work, keep PPE issuance / expiry records, test and calibrate relevant electrical equipment at specified intervals, and maintain a permit-to-work system for high-risk electrical work.
For the detailed electrical-selection logic, see Electrical Safety PPE Malaysia. This data-centre page stays focused on how those controls fit the facility environment.
05 / BATTERY ROOMS
Battery-system risks differ by chemistry and design. A lead-acid / VRLA installation can involve electrolyte splash and gas-management concerns, while lithium-ion systems introduce different thermal-event and off-gas hazards. The correct response plan must come from the battery manufacturer, facility design, fire strategy and site risk assessment not from a generic battery-room PPE kit.
For eyewash placement and portable vs plumbed selection, see Emergency Eyewash Station Malaysia.
06 / CONSTRUCTION, FIT-OUT & ESD
Use certified safety helmets and task-appropriate eye / face protection for overhead work, drilling, cutting and installation activities.
Specify toe protection, slip resistance, electrical / anti-static / ESD properties only where the task and site rules require them.
Use collective protection first and suitable harness / connection / rescue arrangements where personal fall protection is required.
Use only where noise / dust / chemical assessment identifies exposure; do not make generic respirators or earmuffs a universal data-centre rule.
An ESD-safe shoe, wrist strap or garment protects sensitive electronic equipment by controlling static charge. It does not replace voltage-rated electrical PPE for shock or arc-flash hazards. Conversely, dielectric electrical PPE is not automatically an ESD-control product. Follow the facility's ESD-control programme for active data halls and its electrical-safety programme for energised electrical hazards.
For elevated work, see Working at Height Malaysia.
07 / HAISAR DATA CENTRE SUPPLY
The products below are genuine Haisar listings. I used built-in illustrative visuals so the article does not depend on catalogue-image URLs remaining unchanged.

Product details: Haisar listing.
Do not buy these as a fixed “data centre kit”. Arc rating, glove class, LOTO device type and emergency eyewash provision must be selected against the facility's actual electrical / chemical / maintenance requirement.
08 / INSPECTION, DOCUMENTS & CHANGE CONTROL
The 2026 ESMP specifically calls for PPE issuance / expiry records, testing / calibration records for electrical equipment and management-of-change controls where activities or systems can affect electrical safety. Data centre contractors should build those documentation needs into the RFQ rather than chasing them after delivery.
09 / PROCUREMENT MISTAKES & RFQ
Electrical, battery, mechanical, data-hall and fit-out risks are different.
Use the approved incident-energy / arc-rating method rather than nominal voltage alone.
ESD control protects electronics; voltage-rated PPE protects people from electrical hazards.
Battery chemistry, SDS, system design and maintenance task determine the chemical / electrical controls.
A kit can contain the wrong breaker / isolator devices for the actual facility.
Model-specific certificates, ratings and operator submittals can determine whether a product is accepted on site.
Send it to Haisar with the electrical / battery / zone information so the quotation can be built around the actual work package.
10 / FAQ, SOURCES & INTERNAL LINKS
There is no single universal kit. PPE depends on the work zone and task: electrical work, battery rooms, fit-out, mechanical maintenance, data-hall work and external areas have different hazards and controls.
Not for every task. Arc-rated PPE should follow the approved electrical risk / incident-energy assessment or other accepted selection method for the specific equipment and work.
No. ESD / anti-static footwear manages static charge to protect sensitive equipment or control static accumulation; it is not the same as dielectric electrical PPE.
The answer depends on battery chemistry, maintenance task and SDS / system requirements. Chemical splash protection and emergency flushing may be needed for electrolyte exposure, alongside electrical isolation and other battery-system controls.
Yes. Haisar's electrical-safety range includes arc-flash kits, insulating gloves, LOTO padlocks / kits, insulating mats, face protection and related equipment.
