01 / EMERGENCY EYEWASH PLACEMENT
DOSH CHRA / USECHH · ANSI/ISEA Z358.1 · chemical emergency response
Quick answer: place emergency eyewash / shower equipment where the chemical risk assessment says immediate flushing may be needed, then verify that the selected station can be reached quickly, remains unobstructed, suits the eye-only or full-body exposure scenario, and is maintained in working order. DOSH's CHRA framework expects emergency eyewash / shower provision to be available and functional where the hazard requires it. The commonly used 10-second access, 15-minute flushing and weekly activation criteria come from ANSI/ISEA Z358.1—not directly from Malaysian legislation.
This page is positioned as Haisar's main placement / accessibility / maintenance authority page. The separate eyewash-price articles can continue to own pricing and product-type intent.
02 / MALAYSIA REQUIREMENTS
The correct starting point is the workplace's chemical-risk framework—not a generic equipment rule. Under the USECHH Regulations 2000, an employer must make a written health-risk assessment before work that exposes or is likely to expose employees to chemicals hazardous to health. DOSH's CHRA manual then asks, under emergency-response preparedness, whether emergency eyewash and shower equipment is available and in working order.
| Reference | How to apply it |
|---|---|
| USECHH Regulations 2000 | Use the written chemical-health-risk assessment to identify chemical exposures and required controls. |
| DOSH CHRA manual | Emergency-response preparedness includes checking whether emergency eyewash / shower equipment is available and working. |
| SDS / chemical information | Review hazard classification and first-aid / emergency information for the chemicals actually handled. |
| Site / client specification | Projects may adopt ANSI/ISEA Z358.1 or another technical benchmark for location, flow, temperature, testing and performance. |
Important correction to the old article: the Factories and Machinery Act 1967 should not be presented as the current legal basis; it was repealed effective 1 June 2024. ANSI/ISEA Z358.1 is a technical standard, not a Malaysian statute.
03 / PLACEMENT
If ANSI/ISEA Z358.1 is the project benchmark: the station should be reachable within about 10 seconds on the same level / plane and via a clear unobstructed path.
04 / EQUIPMENT TYPE
| Type | Best fit | Important limitation |
|---|---|---|
| Plumbed eyewash | Permanent work areas where eye / face splash is credible and suitable plumbing is available. | Needs adequate water supply, drainage / installation planning and maintenance. |
| Self-contained / portable eyewash | Remote, temporary or mobile work areas where fixed plumbing is not practical. | Fluid volume, preservation / change schedule and working capacity must be managed. |
| Combination eyewash + shower | Areas where the assessed chemical exposure can affect both eyes / face and the body. | Requires correct plumbing, drainage, space, flow and installation. |
| Personal eyewash bottle | Supplementary immediate first-flush provision. | ISEA treats personal units that cannot provide the required 15-minute flow as supplemental rather than primary equipment. |
05 / PLACEMENT BY WORK AREA
Place the primary flushing equipment at the transfer risk area not in a distant corridor or welfare room.
Bench- or wall-mounted units can suit fixed work areas where the CHRA supports the arrangement.
Assess electrolyte splash and maintenance activities, then provide immediate flushing provision appropriate to the risk and room layout.
Remote manifolds, jetties and temporary work may need portable or mobile units where fixed plumbing is impractical.
Acid / alkali cleaning can create eye and body splash exposure; assess whether a combination shower is needed.
Focus on actual handling points—receiving, transfer, decanting and spill-response zones—not only the storage-room entrance.
06 / ANSI/ISEA BENCHMARK
ANSI/ISEA Z358.1-2014 (R2020) is the current version listed by ISEA. It is not Malaysian legislation, but it is widely used as a technical specification for performance, installation and maintenance.
| Criterion | Technical benchmark |
|---|---|
| Travel time | Reach primary emergency flushing equipment within about 10 seconds via a clear path. |
| Flush duration | Primary compliant equipment is designed to sustain approximately 15 minutes of flushing. |
| Eyewash flow | ISEA's guide states 0.4 gpm / 1.5 L/min minimum for an eyewash. |
| Water temperature | ISEA guidance describes tepid flushing fluid, approximately 15.6–37.8°C. |
| Weekly activation | Plumbed units are activated weekly to verify operation and flushing-fluid availability. |
| Annual inspection | A comprehensive annual inspection is recommended against the standard and workplace conditions. |

07 / INSPECTION & MAINTENANCE
Do not apply a plumbed-unit weekly flush procedure blindly to sealed single-use eyewash bottles; each equipment type has a different maintenance method.
08 / HAISAR EYEWASH EQUIPMENT
These are real Haisar-listed products. The cards use built-in sample visuals so the page does not break if catalogue image URLs change.

Product details: Haisar listing.
Floor-mounted combination unit for work areas where the assessed splash hazard can affect eyes / face and body.
Product details: Haisar listing.
Selection principle: station type should follow the chemical risk, work location, plumbing availability, eye-only versus full-body exposure, flow / duration requirement and maintenance plan—not price alone.
09 / COMMON MISTAKES & RFQ
A distant treatment room does not solve the need for immediate flushing at the chemical hazard point.
Pallets, drums, furniture, doors or temporary equipment can make a nearby station unusable.
Personal wash bottles can be supplementary, but they do not replace primary equipment when the adopted standard requires sustained flow.
Portable units need fluid management and sufficient working volume; choose them because they fit the location and hazard.
An eyewash alone may be insufficient where corrosive splash can affect a larger body area.
The CHRA asks whether eyewash / shower equipment is available and working—not merely present.

10 / FAQ, SOURCES & INTERNAL LINKS
If ANSI/ISEA Z358.1 is the adopted benchmark, the primary station should be reachable in about 10 seconds via a clear path. The Malaysian CHRA should first identify whether emergency eyewash / shower provision is required.
No. It is an American National Standard and a widely used technical benchmark. Malaysian compliance should be grounded in applicable law, USECHH / CHRA, SDS information, site requirements and any adopted technical standard.
Use an eyewash where the credible exposure is mainly to the eyes / face. Where full-body chemical splash is credible, the risk assessment may require a combination eyewash and drench shower.
Not where the adopted technical specification requires primary equipment capable of sustained flushing. ISEA guidance treats smaller personal wash units as supplementary.
The site should keep it available and working. Where ANSI/ISEA Z358.1 is adopted, plumbed equipment is activated weekly and a comprehensive annual inspection is recommended. Portable units follow the manufacturer's fluid / inspection schedule.
Yes. Haisar's catalogue includes portable, mobile, wall-mounted, bench-mounted, floor-mounted and combination eyewash / shower equipment.
This is a general workplace placement and procurement guide. Final provision should follow the current CHRA / risk assessment, SDS information, site / client requirements, adopted technical standard, manufacturer instructions and actual installation conditions.
