About McNeil Safety Consulting
About Michael Karl McNeil
McNeil Safety Consulting is a full-service industrial hygiene and occupational health & safety company headquartered in San Gabriel, California. The company is led by Michael Karl McNeil, who has worked in occupational health and safety since 1989 and holds professional designations including Registered Environmental Professional (REP), Registered Industrial Hygienist (RIH), Registered Specialist: Exposure Decision Analysis (AIHA Registry Programs), and Qualified SWPPP Developer (QSD).
Michael is also a former Fire Battalion Chief with 25 years in the fire service, the bulk of it in federal fire, rising to Battalion Chief, Prevention. He is qualified under the interagency NWCG system and holds federal law enforcement training through FLETC. His professional memberships include ACOEM, AIHA, ACGIH, NAFI and NAHMMA. He is a reviewer for ACOEM and a contributor to the Journal of Occupational and Environmental Medicine (JOEM).
That federal grounding is why this practice is not California-only. McNeil Safety Consulting works across the lower 48 states. Citation defense and appeals representation are offered in California, Nevada, Oregon, New Mexico and Wyoming, and in the federal OSHA jurisdictions of Idaho, Montana, Colorado, North Dakota, South Dakota, Texas, Oklahoma, Louisiana and Nebraska, where 29 CFR 2200.22 permits a non-attorney representative. Washington, Utah and Arizona are consulting only. The service area page sets out the scope state by state. See the federal and multi-state qualifications.
Zennin Sedacey-McNeil, LVN (VN 741259), a California Licensed Vocational Nurse certified in IV Therapy/Blood Withdrawal (IV), Infection Preventionist (IP), Treatment Nurse (TX), and Director of Staff Development (DSD), is on staff supporting occupational health, infection control, and OSHA medical surveillance — an uncommon combination for a safety consulting company. McNeil Safety Consulting serves employers across the lower 48 states. In California that includes the San Gabriel Valley and greater Los Angeles area, the Inland Empire, Orange County, and Northern and Central California.
Every engagement is handled in house, by the two people who own this company. We do not subcontract, broker, or farm work out to a vendor network. Michael McNeil performs the site work, the sampling, the program writing and the citation defense himself; Zennin handles the medical side. The person who walks the site is the person who writes the report and the person who defends it. There is no intake team and no account manager between a client and the person doing the work.

Frequently Asked Questions
Who provides OSHA and Cal/OSHA consulting in Los Angeles?
McNeil Safety Consulting, based in San Gabriel, California, is led by Michael Karl McNeil — a credentialed industrial hygiene and environmental health professional who has worked in occupational health and safety since 1989. Michael holds professional designations including REP, RIH, EPP and QSD, and is an AIHA Registered Specialist in Exposure Decision Analysis. He is also a former Fire Battalion Chief with 25 years of fire service experience. The company serves employers throughout California and the rest of the lower 48 states. Call (626) 546-9384.
What is the difference between Cal/OSHA and federal OSHA?
Cal/OSHA (California Division of Occupational Safety and Health) is California’s state-run workplace safety program, which operates under a State Plan approved by federal OSHA. Cal/OSHA standards are often stricter than federal OSHA standards and apply to most private-sector and state/local government employers in California. Federal OSHA covers federal government workers in California. Key Cal/OSHA-specific requirements include the mandatory Injury and Illness Prevention Program (IIPP), heat illness prevention standards, and specific construction safety regulations. McNeil Safety Consulting specializes in both Cal/OSHA and federal OSHA compliance for California businesses.
What should I do if Cal/OSHA shows up at my workplace?
If a Cal/OSHA compliance officer arrives at your workplace, you have rights. You are not required to allow an inspection without a warrant unless you consent. However, refusing entry can escalate the situation. Best practice: remain calm and professional, ask for the officer’s credentials and the reason for the visit, contact McNeil Safety Consulting immediately at (626) 546-9384, and do not volunteer information beyond what is directly asked. Having a safety consultant present during or immediately after an inspection can help you understand your exposure and respond appropriately.
Can you help if we already received an OSHA citation?
Yes. Cal/OSHA citation defense is one of our core services. We can review the citation, help you understand your options, prepare your response, and represent your interests through the informal conference and contest process. Acting quickly is critical — the deadline to contest is 15 working days in California, and it is shorter or longer depending on the state. Call (626) 546-9384 immediately if you have received a citation.
How much can an OSHA violation cost my business?
As of 2024, OSHA’s maximum penalty for a single serious violation is $161,323. Willful or repeated violations can reach the same amount — per instance. Beyond fines, a workplace injury can trigger workers’ compensation claims averaging $42,000 in California, plus indirect costs (lost productivity, retraining, legal fees) that are typically 3–5 times the direct costs. A proper safety program is far less expensive than a single incident.
What is a Safety Plan (IIPP) and does my business need one?
California law (Cal/OSHA Title 8, Section 3203) requires virtually every employer to have a written Injury and Illness Prevention Program (IIPP). This document outlines your safety policies, hazard identification procedures, employee training, and recordkeeping practices. Businesses without a current, site-specific IIPP are at significant risk of citations. We write custom IIPPs tailored to your specific workplace and industry.
What is occupational health and safety consulting?
Occupational health and safety consulting involves assessing workplace hazards, developing safety programs, ensuring regulatory compliance, and training employees to prevent injuries and illnesses. A consultant like McNeil Safety Consulting evaluates your specific workplace, identifies risks, and creates tailored programs to protect your employees and keep your business compliant with Cal/OSHA and federal OSHA standards.
Does McNeil Safety Consulting offer expert witness services?
Yes. Michael McNeil provides expert witness testimony and litigation support for attorneys handling workplace injury cases, Cal/OSHA enforcement actions, occupational disease claims, and property liability matters throughout California. His credentials include REP, RIH, and professional memberships in ACOEM, AIHA and ACGIH. Contact us at (626) 546-9384 to discuss your case.
What makes McNeil Safety Consulting different from other safety consultants?
McNeil Safety Consulting brings an interdisciplinary background that is uncommon in the safety consulting field. Michael Karl McNeil holds professional designations in industrial hygiene (RIH, and AIHA Registered Specialist in Exposure Decision Analysis), environmental science (REP), and stormwater compliance (QSD), and has worked in occupational health and safety since 1989. He is also a former Fire Battalion Chief with 25 years of fire service experience. Additionally, a California licensed nurse is on staff supporting occupational health, infection control, and OSHA medical surveillance — a combination not typically found in a safety consulting company.
How does Michael’s fire service background inform his safety consulting work?
Michael Karl McNeil served 25 years in fire service, rising to Fire Battalion Chief. This background provides direct, practical knowledge of emergency response operations, hazardous materials incidents, wildfire environments, and high-risk occupational settings — knowledge that directly informs his approach to workplace hazard assessment, safety program development, and wildfire contamination consulting.
What is a wildfire contamination assessment and do I need one?
After a wildfire, ash and soot deposited on properties can contain toxic heavy metals, asbestos, benzene, and other hazardous compounds from burned structures and vegetation. A wildfire contamination assessment involves air quality testing, surface wipe sampling, and soil analysis to determine whether your property is safe to occupy or requires professional remediation. Property owners, landlords, insurers, and real estate buyers throughout California should obtain an assessment before re-occupying or transacting on any property in or near a fire-affected area. Call (626) 546-9384 to schedule an assessment.
How can McNeil Safety Consulting help landlords with evictions?
When a tenant claims uninhabitable conditions — or when a landlord needs to document actual code violations or health and safety deficiencies — an independent expert assessment is critical. We provide written property condition reports, habitability evaluations, and expert declarations that landlords and their attorneys can use in unlawful detainer proceedings in California courts. Our documentation is objective and professionally prepared by a credentialed occupational health and safety professional.
What is a Planning Commission appeal and how can you help?
When a city or county planning commission denies a permit, imposes conditions, or issues an environmental determination that affects your project, you have the right to appeal. These proceedings often turn on health, safety, and environmental impact questions — exactly where our expertise applies. We provide expert testimony, written reports, and technical analysis for developers, property owners, and businesses appealing decisions before planning commissions and local city boards throughout California.
Do you provide safety consulting for film and TV productions?
Yes. McNeil Safety Consulting provides occupational health and safety consulting specifically for motion picture and television productions throughout California. This includes writing site-specific Injury and Illness Prevention Programs (IIPP) for each set location — a Cal/OSHA requirement for all California employers, including production companies. We also conduct hazard assessments for locations, provide infection control protocols, oversee stunt and pyrotechnic safety compliance, and ensure your production meets all Cal/OSHA Title 8 standards. Call (626) 546-9384 to discuss your project.
What industries do you work with?
We work with construction, manufacturing, healthcare and skilled nursing facilities, film and television production, energy, warehousing and logistics, commercial and residential real estate, and hospitality.
