Only when: splash risk
Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 recommends safety glasses with side shields as minimum protection, and tight-fitting goggles or a face shield if splashes are likely. Section 2 carries no eye-hazard GHS code at mixture level (the ingredient-level Eye Dam. 1 classification on the under-1% additive component does not elevate to the mixture), so this reflects a real splash-contact precaution during pour and drain, not a mixture-level corrosive-eye hazard.

Translated from the manufacturer’s Safety Data Sheet, Section 2
SDS Section 2 classifies the mixture Warning, Skin Sensitization Category 1 (H317) at the mixture level, driven by the alkyl ester carboxylic acid additive. Section 7 and Section 8 both direct wearing protective gloves and clothing, naming neoprene or nitrile glove types specifically. This is a real mixture-level sensitization hazard, not boilerplate, so gloves are recommended for routine handling, not just a splash precaution.
U.S. regulatory standard
29 CFR 1910.138(a); 1910.132(d)
“appropriate hand protection when employees' hands are exposed to hazards such as those from skin absorption of harmful substances.”
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

Only when: in enclosed space
Translated from the manufacturer’s Safety Data Sheet, Section 8
Section 2 carries no H330/H331/H334/H335 at mixture level, and Section 9 confirms the fluid is non-volatile at ambient temperature (flash point above 165 degrees C, COC). Section 8's respiratory language ('If exposure limits are exceeded or irritation is experienced, NIOSH/MSHA approved respiratory protection should be worn') is standard SDS boilerplate rather than a scenario-specific control. The situational tier translates that boilerplate into a cautious precaution for pouring or draining fluid in a closed garage, not a mixture-level inhalation hazard.

PPE tiers translate the manufacturer’s SDS and U.S. regulatory standards. Not professional safety advice. How we report safety.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR Engineered to meet Toyota's WS transmission spec, but Idemitsu holds no Toyota license or approved-products listing, so treat this as a compatibility claim, not a verified approval. No independent data confirms shudder resolution for this fluid. The SDS lists a Warning skin sensitizer hazard (H317); nitrile or neoprene gloves are a real call during the fill.
Idemitsu ATF Type TLS-LV is the newer, lower-viscosity fluid in Idemitsu's WS-family lineup, sold as meeting Toyota's WS specification for Toyota, Lexus, and Scion automatics. No Toyota approval number or approved-products listing backs it; the label's own phrasing, engineered for and meets requirements of WS, is a compatibility claim, not a verified equivalent to Toyota's Genuine WS fluid. No independent reports confirm shudder outcomes or service life for this SKU.
The fit is Toyota, Lexus, and Scion owners with WS-spec automatics who want a lower-cost fluid from an established lubricant manufacturer and accept an unlicensed compatibility claim over Toyota's own licensed fluid. Owners wanting that documentation weight should use the OEM fluid instead; this isn't for Honda-spec transmissions, Idemitsu's separate Type H Plus fluid covers those.
The SDS classifies this fluid Warning for a skin-sensitizing additive (H317); nitrile or neoprene gloves are a real call for routine handling. Section 15 discloses a trace, well under 0.1 percent Proposition 65 benzene impurity. The SDS doesn't classify aquatic toxicity at the mixture level; the base stock reads as conventional mineral oil. Take spent fluid to a used-oil collection facility; don't pour it down a drain.
No. Idemitsu markets Type TLS-LV as engineered for and meeting the requirements of Toyota's WS specification, but it carries no Toyota-issued license number and no confirmed listing on a Toyota approved-products list. It is a separate manufacturer's own WS-compatible formulation, not a rebadged or licensed version of Toyota's Genuine ATF WS.
TLS-LV is the newer, lower-viscosity fluid in Idemitsu's WS-family lineup. It targets the same Toyota, Lexus, and Scion WS-spec automatics as older WS-family fluids, but the formulation is not confirmed byte-identical to Toyota's own Genuine ATF WS; treat any WS-family fluid, including this one, as a compatibility claim rather than a licensed equivalent.
The SDS classifies the mixture Warning for a skin sensitizer hazard (H317), traced to a corrosion-inhibiting additive. Section 8 of the SDS names neoprene or nitrile gloves specifically, so gloves are a real recommendation for routine handling, not just a splash precaution.
The SDS's Section 15 discloses a trace amount of benzene, under 0.001 percent by weight, on its own Proposition 65 warning label. That trace-level regulatory disclosure is the basis for the warning; Amazon's listing data did not reflect it.
No. Type H Plus is Idemitsu's Honda-family CVT and automatic transmission fluid, a different formulation for a different set of specifications. TLS-LV is built and marketed specifically for Toyota, Lexus, and Scion vehicles requiring the WS specification; the two products are not interchangeable.
