Emergency Eyewashes and Showers

Scope

This standard covers the minimum mandatory requirements governing the design, and installation and inspection of emergency eyewash and shower that are permanently installed (including fixed and self-contained units) at company facilities. These are designated for the emergency first-aid treatment of personnel exposed to injurious chemicals and permanent “high dust work areas” as determined by proponent organizations (e.g., permanent sand blasting site, etc.) and Industrial Hygiene Unit of EPD.

Note: The requirements for temporary emergency eyewash and showers (i.e., “portable”

units) for construction and maintenance activities are identified in the Saudi Aramco Construction Safety Manual (SACSM,), and are available as standard equipment in B2B, which are outside the scope of this document.

Conflicts and Deviations

Any conflicts between this document and other applicable Mandatory Saudi Aramco Engineering Requirements (MSAERs) shall be addressed to the EK&RD Coordinator.

Any deviation from the requirements herein shall follow internal company procedure SAEP-302.

Emergency Eyewashes and Showers

6.2

Self-Contained Units Flushing Fluid Requirements and Inspections

6.2.1 The flushing fluid in self-contained units shall use an isotonic saline

solution 0.85% to 1.0% NaCl buffered to a pH from 7.3 to 7.4 and preserved with a suitable anti-bacterial agent or other alternative as approved by Environmental Compliance Division / Environmental Protection Department.

6.2.2 The changing or recharging of flushing fluid in these devices and their overall maintenance shall meet the manufacturer’s instructions to avoid dangerous build-up of contaminants.

6.2.3 Maintenance records shall be maintained and be readily available.

6.3

Flow Capability and Duration

6.3.1 Water supply systems shall be capable of providing flow for a duration

of at least 15 minutes to the involved eyewashes and showers at the flow rates and pressures specified herein in accordance with the requirements of ANSI/ISEAZ358.1 (section 4 & section 5).

6.3.2 A combination eyewash/shower unit shall be capable of flowing through

both units simultaneously with the flow rate, pressure, and temperature requirements specified herein.

6.3.3

If more than one eyewash, or combination eyewash/shower unit could be used simultaneously, the system shall be capable of such usage with the flow rate and pressure requirements specified herein.

6.3.4 Water supply systems shall be continuously available for use when

release of an injurious chemical is possible.

6.3.5 Eyewash nozzles shall be protected with covers, which can be easily

removed, to prevent nozzle contamination and clogging.

6.4 Water Temperature, Pressure, and Flow Rates

6.4.1 The delivered water temperature at eyewashes and safety showers shall not exceed 38°C (100°F) at any time, except for the short duration when warmer water is being flushed out of the piping between an aboveground operating valve and the eyewash nozzles after opening the valve.

Commentary Note:

Over the years, Loss Prevention has recommended to bury piping upstream of the eyewash/showers to control high temperatures, a practice that is simple and often works to bring the water temperature down enough to satisfy this Standard (insulating the piping and leaving it

Emergency Eyewashes and Showers

aboveground seldom, if ever, works). Solar radiation on aboveground piping heats the water and therefore buried piping is preferred. In some situations, even buried piping may exceed the safe limit. In situations where coolers are considered, there has been some question about the need to use such an expensive (and high-maintenance) solution. While water coolers are acceptable (outside of electrically classified areas), before using a cooler, consult with the Environmental Compliance Division and the Chief Fire Prevention Engineer or his representative to see if there may be a better solution.

6.4.2 The delivered water temperature shall not be less than 16°C (60°F)

except during initial activation of the eyewash or eyewash/shower unit, when a lower temperature is permitted during the period necessary to flush the aboveground piping immediately in the vicinity of the eyewash or eyewash/shower unit.

6.4.3 Required pressures and flow rates are covered in ANSI/ISEAZ358.1

(section 4, 5 & 6) which is part of this Standard.

6.5

Pressure Control

Permanently installed emergency eyewashes shall be designed to ensure that eyes will not be injured due to excessive water velocity. Pressure controllers or self-regulating orifices should be utilized if the water supply pressure exceeds the 207 kPa, tolerance of +3.4 kPa to -0kPa (30 psig, tolerance of +0.5 psi to -0 psi) design flowing pressure in ANSI/ISEAZ358.1 section 4, section 5, section 6 & section 8, unless the water supply system is designed such that this pressure could not be exceeded. A permanently installed pressure gage is to be provided to the water supply to emergency eyewashes and showers to verify supply pressures.

6.6 Water Supply Systems Requirements

The water supply system shall be designed as a potable water system in accordance with SAES-L-310, SAES-S-040, SAES-S-060, and SAES-S-070 for design requirements including cross-connection constraints and backflow preventer requirements between potable water and other systems.

Installation

7.1

General

All installations shall meet the requirements of this Standard and ANSI/ISEA Z358.1 (sections 4 through 8).

Location

7.2.1 Emergency eyewashes and showers shall be located as follows:

In accessible locations that require no more than 10 seconds to reach [no closer than 3 m (10 ft) nor further than 15 m (50 ft) from a hazard except where specifically allowed below]. The nature, severity, and environment of the chemical hazard shall be considered in determining the maximum allowable unobstructed distance. For severe hazards, consult with the Industrial Hygiene Unit and Medical Services to determine the proper distance.

b. Outside of the most likely spray paths such as sample and drain

points.

c. Along or adjacent to the normal path of egress, free of obstructions,

and on the same floor level as the hazard.

In a location accessible from the hazard without the use of stairs, a ladder or a door.

e. Upwind, based on the prevailing wind, of the hazard where practical.

In more than one place in the vicinity of the hazard if more than one person is likely to be splashed at the same time.

In an area that is well illuminated area lighted (100 lux minimum; refer to SAES-P-123, Table-4).

h. At a safe distance at least 3 m (10 ft) from electrical equipment and

power outlets that are not protected by ground-fault circuit- interrupters (GFCIs), except in battery rooms, in which case separation between an eyewash (no shower) and the batteries shall be at least 1.5 m (5 ft). Only an eyewash is required in the battery room, provided that there is no acid-mixing activity to be done inside the battery room. If a shower is provided with the eyewash, then 3 m (10 ft) separation is required.

     Commentary Note:

Topping-up batteries with electrolyte or distilled water is not considered acid mixing.

Exception:

Dry type battery or Sealed Valve Regulated Batteries installations do not require eyewashes.
