Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8.2 states 'Avoid contact with the eyes' and specifies safety glasses. No H318 or H319 at §2 mixture level. Drip/squeeze bottle · splash is the realistic exposure route, not aerosol mist.”

TL;DR DANGER-rated aspiration hazard · do not swallow; do not induce vomiting if ingested. Wear nitrile gloves during extended handling. Community-confirmed months of lubrication and corrosion protection per application from this MIL-SPEC synthetic formula.
Break-Free CLP cleans fouling, lubricates moving parts, and protects metal from corrosion in one squeeze bottle. MIL-PRF-63460F qualification covers extreme temperatures, saltwater, and high-cycle stress. Owners report lubrication lasting several months on hinges, tools, and mechanical assemblies. The synthetic PAO base leaves a thinner, less tacky film than petroleum-distillate lubricants. The corrosion inhibitor package is the primary differentiator from lighter petroleum oil sprays.
Good fit for firearms, tools, and outdoor hardware that need one product to lubricate and protect against rust for months. The squeeze bottle works well for targeted application on hinges, pivot points, and cable guides. Skip it if you need aerosol coverage or a penetrating spray for rusted fasteners.
H304 (aspiration hazard) drives the DANGER signal word · this is a swallowing hazard, not a vapor-inhalation hazard. Do not induce vomiting if ingested; seek medical attention. SDS §8 states respiratory protection is not required under normal use. Flash point above 94°C; negligible vapor pressure from a squeeze bottle.
SDS §12 states the product is biodegradable. No aquatic toxicity classification at the mixture level. SDS §15 lists no Prop 65 substances.
No specific material compatibility warnings appear in the SDS. The synthetic PAO base is generally considered safe on most metals, hard plastics, and nylon. Exercise caution with natural rubber seals · PAO-based lubricants may affect some natural rubber formulations over prolonged contact.
No · SDS §15 from manufacturer Safariland LLC explicitly lists no Prop 65 substances. The product listing shows a Prop 65 flag, but this appears to conflict with the manufacturer's own SDS. The SDS is the authoritative source for ingredient-level hazard classification.
The DANGER signal word comes from H304 · a classification indicating the liquid can be fatal if swallowed and enters the airways (aspiration hazard). This is a swallowing risk, not a vapor-inhalation risk during normal application. The SDS explicitly states respiratory protection is not required under normal use conditions.
The SDS from manufacturer Safariland LLC identifies a synthetic PAO (poly-alpha-olefin) base · listed as 1-decene, dimer, hydrotreated · plus an organic calcium salt corrosion inhibitor. This is a fully synthetic formula, not a petroleum-distillate lubricant.
Yes · it is formulated as a general metal lubricant, cleaner, and corrosion protector. Owners report using it on household hinges, tools, and other metal mechanisms. The MIL-SPEC synthetic formula makes it effective for any metal mechanism needing lubrication and rust protection.
