Published by SALUSWhen handling hydrofluoric acid, it is crucial to use appropriate personal protective equipment (PPE) to prevent exposure to this highly corrosive and toxic chemical. According to OSHA standards, the following PPE is generally required:
- Eye and Face Protection: Use chemical splash goggles and a face shield to protect against splashes and vapors that can cause severe eye and skin damage [1].
- Skin Protection: Wear chemical-resistant gloves, such as those made from neoprene or nitrile, to prevent skin contact. Additionally, use a chemical-resistant apron or full-body suit to protect against spills and splashes [2].
- Respiratory Protection: If there is a risk of inhaling vapors, use a respirator with appropriate cartridges for acid gases. In environments where the concentration of hydrofluoric acid vapors is high, a full-facepiece respirator or a powered air-purifying respirator (PAPR) may be necessary [3].
- Foot Protection: Wear chemical-resistant boots to protect your feet from spills and splashes [4].
Employers are responsible for conducting a hazard assessment to determine the specific PPE required based on the concentration and form of hydrofluoric acid being handled, as well as the specific work environment [2]. Additionally, training on the proper use, limitations, and maintenance of PPE is essential to ensure safety [4].

The employer shall not require an employee to provide or pay for his or her own PPE, unless the PPE is excepted by paragraphs (h)(2) through (h)(5) of this section. - (7) This paragraph (h) shall become effective on February 13, 2008. Employers must implement the PPE payment requirements no later than May 15, 2008. NOTE TO §1910.132(H): When the provisions of another OSHA standard specify whether or not the employer must pay for specific equipment, the payment provisions of that standard shall prevail.

Detachable side protectors (e.g. clip-on or slide-on side shields) meeting the pertinent requirements of this section are acceptable. - (3) The employer shall ensure that each affected employee who wears prescription lenses while engaged in operations that involve eye hazards wears eye protection that incorporates the prescription in its design, or wears eye protection t…
