Emergency eyewash and showers: what section 5162 actually requires

A corrosive splash does not give anyone time to look for help. California's requirement is written around that fact, and it is stricter and more specific than most employers realize. Two separate sections of Title 8 apply, and an employer can satisfy one while violating the other.

Section 5162 sets the equipment standard

Section 5162 governs emergency eyewash and shower equipment. Subsection (a) requires eyewash facilities meeting ANSI Z358.1-1981 where the eyes of an employee may be exposed to corrosive or toxic substances. The subsection then closes a gap that turns up on inspection after inspection: water hoses, sink faucets, or showers are not acceptable eyewash facilities. Personal eyewash units are permitted, but only as a supplement to the required equipment, never in place of it.

Subsection (b) carries the same logic to the body. Where skin may be exposed to corrosive or toxic substances during routine operations or foreseeable emergencies, an emergency shower complying with ANSI Z358.1-1981 is required.

Ten seconds, and nothing in the way

Subsection (c) is the one that decides most citations. Eyewash facilities and deluge showers have to be in accessible locations requiring no more than 10 seconds for the injured person to reach. Where both an eyewash and a shower are called for, they must be positioned so one person can use them at the same time, and the path and the area around them must be kept clear of obstructions.

Ten seconds is a distance measured by a person who cannot see. It is not a tape measure run by someone with both eyes open, and it does not survive a pallet parked in the aisle, a door that latches, or a step up onto a platform. Walk the route blind and time it; that is the only reading of subsection (c) that holds up.

Water quality and the hands-free valve

Subsection (d) requires potable water delivered at the flow rates the referenced standard specifies, and requires the control valve to stay activated without hand pressure once opened, until it is intentionally shut off. Hand-held drench hoses are the exception. The reason is practical: a person holding their eyelids open cannot also hold a valve down.

The monthly activation is a written duty

Subsection (e) requires plumbed eyewash and shower equipment to be activated at least monthly, both to flush the line and to verify that the unit works. Self-contained units are maintained per the manufacturer's instructions instead.

Monthly activation is the single most commonly missed item in this section, and it is also the easiest to document. A tag on the unit with a date and an initial is enough to show it happened. Without one, an employer is arguing from memory against an inspector's notes.

Section 3400(d) is a separate, independent duty

Employers who have read section 5162 often stop there. Section 3400 imposes obligations of its own. Subsection (d) requires that where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body be provided within the work area for immediate emergency use.

Within the work area is its own test. A compliant fixture in the next building, or down a corridor and through a door, does not meet it, and the fact that the fixture itself satisfies section 5162 is no answer.

The rest of section 3400 fills out the medical services picture. Subsection (b) requires an adequately trained first aid provider where there is no infirmary, clinic, or hospital in near proximity used for treating all injured employees. Subsection (c) requires adequate first aid materials approved by the consulting physician, readily available on every job and kept in sanitary and usable condition. Subsection (f) requires effective provisions made in advance for prompt medical treatment of a serious injury or illness, avoiding unnecessary delay.

What a walkthrough should confirm

Identify every location where corrosive or toxic contact is foreseeable, not merely where chemicals are stored. Time the route to each fixture as an injured person would travel it. Confirm the eyewash is a fixture and not a faucet, a hose, or a squeeze bottle standing alone. Open the valve and confirm it stays open. Check the tag for a monthly date. Then ask the section 3400(d) question separately: is the facility within the work area?

An eyewash that meets every dimension of the referenced standard and sits behind a closed door thirty seconds away is a citation waiting to be written, and worse, it is an injury that will not be flushed in time.

Rebutting the serious-violation presumption under Labor Code 6432

The single word that decides what a Cal/OSHA citation costs is its classification. A general violation and a serious violation can describe the same condition on the same day and differ by an order of magnitude in penalty. Under the penalty schedule operative 1 January 2025, a general or regulatory violation runs up to $16,285, while a serious violation runs up to $25,000 from an $18,000 base, and a willful or repeat violation reaches $162,851. So the classification is where the argument belongs. And the law puts the employer on the back foot before it starts. The presumption Labor Code section 6432(a) creates a rebuttable presumption that a serious violation exists if the Division demonstrates that there is a realistic possibility that death or serious physical harm could result from the actual hazard created by the violation. Note how little that requires. Not that harm occurred. Not that harm was likely. A realistic possibility that it could result. In practice the Division...

Michael Karl McNeil: the professional record, in one place

My name is Michael Karl McNeil. I work in environmental health and safety, industrial hygiene, emergency planning and forensic consulting, and I have been in occupational health and safety since 1989. This page is my own account of that record, written by me and kept current. Two careers, in order The first was the fire service — twenty-five years of it, ending as a Fire Battalion Chief. I came up through fire prevention, advanced to Fire Prevention Captain and then to Battalion Chief in a federal fire organization. Assignments took me across the country, most of them in the Western states, working under whichever state's rules governed the ground I was standing on. That is where the multi-state side of what I do now comes from: it is not a marketing radius, it is where I have actually worked. The qualifications from those years that still matter are the incident ones — hazardous materials specialist and hazardous materials incident commander, wildland qualifications carried ...

Cal/OSHA Noise Exposure: The 85-Decibel Line That Starts a Hearing Conservation Program — Michael Karl McNeil

By Michael Karl McNeil, REP, RIH, EPP, QSD Most California employers know that noise is regulated. Fewer know that Title 8 draws two different lines, at two different levels, and that the lower of the two is the one that creates most of the obligations. Article 105 of the General Industry Safety Orders, Sections 5095 through 5100, sets a permissible exposure limit at 90 decibels and an action level at 85. The 90-decibel line governs what you must do about the noise itself. The 85-decibel line governs what you must do about the people exposed to it, and that is the hearing conservation program. The two numbers Section 5095(b) defines the action level as an 8-hour time-weighted average of 85 decibels measured on the A-scale, slow response, or the equivalent dose of fifty percent. Section 5096 sets the exposure limits in Table N-1: 90 dBA for eight hours, with the permitted time halving for every five decibels above that, so 95 dBA is limited to four hours and 100 dBA to two.
