California gives an employer eight hours to report a death or serious injury to Cal/OSHA, and section 330(h) leaves a treated-and-released emergency room visit outside the duty. The other clocks that start at the same moment run one working day, two working days, five days, seven days and five years.

Title 8 section 5141.1 turns on at a current AQI for PM2.5 of 151 and nothing else. What the AQI check, the communication system, the Appendix B training, the control hierarchy and the respirator rule mean on a crew working a span, which of the five exemptions a tree crew can actually claim, what the emergency clause does for restoration work, and where Cal/OSHA's own conversion table stopped agreeing with the AQI the EPA publishes.

Section 3395 applies to all outdoor places of employment, and a crew clearing a 12 kV lateral is one of them. What the water, shade, cool-down rest, high-heat, emergency response, acclimatization, training and written plan requirements mean on a crew that moves every hour, which of the five listed industries that crew is in, and what the Division's own enforcement policy says it will look at on any inspection.

California puts traffic control for tree work in one sentence of the General Industry Safety Orders, and that sentence points at the Construction Safety Orders. What sections 1598 and 1599 require, which edition of the California MUTCD they name, what the flagger has to be trained on and hold, and where the flagging duty collides with the second person section 2951(d) already demands.

California's tree work article never names an item of protective equipment for a chain saw operator. This is where each item is actually written — Article 10 of the General Industry Safety Orders, the federal PPE standards in Subpart I, the logging standard that requires chaps and does not reach a tree crew, and ANSI Z133-2026 section 3.3.

California requires an employee in an elevated aerial device to be secured to the machine, and prints the rule twice. The federal standard removed the body belt answer in 2014 and again in 2017. What may be worn, what it attaches to, and what the daily record has to show.

California requires two people trained in first aid and CPR at any work location with two or more employees, and gives a new hire 90 days. The federal rule counts the same two and hides CPR in a definition. Where the one person exception reaches, and where it does not.

California requires the employer to document training to certify satisfactory completion before an employee works unsupervised, and section 3203 says what that documentation has to name. Four fields, a one year retention floor, and a credential built on eighteen months of history.

California requires a written rescue procedure and aerial rescue training in one sentence of section 3421(l). The federal standard never uses the words. What the second person has to be able to do, what a drill has to demonstrate, and why no rule anywhere sets a time to the ground.

A line clearance trainee works on borrowed standing, and the loan runs for exactly as long as the supervision does. Where California puts the condition, where the federal standard puts it, what direct supervision has been held to mean, and the four questions an Appeals Board asked an employer who could not answer them.

Article 12 of the General Industry Safety Orders is the tree work rulebook that keeps applying after Article 38 takes the conductor. Nine sections, 38 defined terms, a climbing line spec, a felling geometry, and five subsections that send the reader somewhere else in Title 8.

Section 2951 of Title 8 is California's work practice rule for line clearance tree trimming. What each of its nine subsections requires, who may perform the operation, where the approach distance actually comes from, what the April 1, 2018 amendment changed, and what the section leaves to other orders.

TCIA's Electrical Hazards Awareness Program is a one-year online credential with a 35-foot aerial rescue attached. What it covers, what it costs, what OSHA changed in 2014 that the program page still describes the old way, and what belongs in the file behind the certificate.

ANSI Z133-2026 replaced the old incidental and utility line clearance split with four Electrical Levels, each with its own minimum approach distance table. What the standard requires, who it binds, where it differs from Cal/OSHA Table 1, and where OSHA's enforcement guidance now points at text that no longer exists.

OSHA's own word for tree work near a conductor that nobody at the utility ordered is incidental, and the word appears only in a preamble footnote. What it takes you out of, what it does not take you out of, and why the California answer is different.

The federal standard sorts everyone working near an energized conductor into three tiers, and it does the sorting in a scope paragraph rather than in paragraph (r). This is where each tier is written, what training each one carries, and the distance each one owes the same 12 kV conductor.

Title 8 defines two tree-work credentials in two different sets of safety orders. One carries an 18 month clock and opens primary conductors; the other carries no clock, must be present at every work location, and stops at 1 foot from 600 volts.

Cal/OSHA Title 8 section 2950 sets the trigger for Article 38 and the minimum approach distances owed by everyone on a line clearance job who is not a qualified tree trimmer or trainee, with three exceptions and one table whose rows are arithmetic.
