Reasons for PPE

Personal Protective Equipment (PPE) “Protective equipment, including personal protective equipment for eyes, face, head, and extremities, protective clothing, respiratory devices, and protective shields and barriers, shall be provided, used, and maintained in a sanitary and reliable condition wherever it is necessary by reason of hazards of processes or environment, chemical hazards, radiological hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact.”

PPE

EYE PROTECTION “The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation.”

EYE PROTECTION Chemical Handling – Splash Hazard Splash Goggles, eyecup and cover types. For severe exposure, use face shield. See notes (3), (11).” (3) Face-shields should only be worn over primary eye protection (spectacles or goggles). (11) Ventilation should be adequate, but well protected from splash entry. Eye and face protection should be designed and used so that it provides both adequate ventilation and protects the wearer from splash entry.

Protective Eyewear

GLOVES Selection guidelines for hand protection. Gloves are often relied upon to prevent cuts, abrasions, burns, and skin contact with chemicals that are capable of causing local or systemic effects following dermal exposure. OSHA is unaware of any gloves that provide protection against all potential hand hazards, and commonly available glove materials provide only limited protection against many chemicals. Therefore, it is important to select the most appropriate glove for a particular application and to determine how long it can be worn, and whether it can be reused.

GLOVES With respect to selection of gloves for protection against chemical hazards: (A) The toxic properties of the chemical(s) must be determined; in particular, the ability of the chemical to cause local effects on the skin and/or to pass through the skin and cause systemic effects; (B) Generally, any "chemical resistant" glove can be used for dry powders; (C) For mixtures and formulated products (unless specific test data are available), a glove should be selected on the basis of the chemical component with the shortest breakthrough time, since it is possible for solvents to carry active ingredients through polymeric materials (D) Employees must be able to remove the gloves in such a manner as to prevent skin contamination.

REACT-OX® Chemical Resistant Gloves Nitrile type or similarOther compatible with Sulfuric Acid and Sodium Hydroxide

MINIMUM PPE A work uniform affording minimal protection, used for nuisance contamination only. Chemical resistant gloves. Boots/shoes, chemical-resistant steel toe and shank. Safety glasses or chemical splash goggles. Hard hat.

WHEN TO USE MINIMUM PPE Pump draw downs. Water Board maintenance/ repair. Probe calibration.

RECOMMENDED PPE Chemical-resistant clothing (i.e.: overalls and long-sleeved jacket; coveralls; one or two-piece chemical-splash suit; disposable chemical- resistant overalls). Chemical-resistant Gloves. Boots, outer chemical-resistant, steel toe and shank or boot-covers, outer chemical-resistant (disposable) over standard PPE boots. Hard hat. Tight fitting safety glasses with side shields or chemical splash goggles. Face shield.

WHEN TO USE RECOMMENDED PPE Repairing Leaks and pumps (if line, fittings and/or pump is unhooked from chemical source and flushed with water-minimum PPE can be used). Tote exchange. Chemical clean up.

Tychem® Protective Suit (Acid Resistant)

TOTE RECEIVING AND EXCHANGE SOP 1. Review Tote Condition Check valve for visible damage obtained during shipping. Do not use if damaged 2. Move tote from storage area to chemical room 3. Don Chemical PPE appropriate to Material being handled.

TOTE RECEIVING AND EXCHANGE SOP 4.With PPE on, remove the cover cap and any plastic or foil seal on the bottom valve. 5.Use Lock-out Tag-out. Turn off and unplug chemical pump or pumps. 6.Shut off bottom valve on old tote and any valve on the chemical line at the tote.

TOTE RECEIVING AND EXCHANGE SOP 7. Remove cam lock fitting and drain any chemical found in cam lock fitting into a plastic catch bucket. Set tote fitting and chemical line in bucket and in a secure out of the way location. 8. Replace cap on the bottom valve of the old tote. 9. Remove old tote from chemical room. 10. Move new tote into position in the chemical room.

TOTE RECEIVING AND EXCHANGE SOP 11. If female CAM was leaking, replace seal now. 12. Lock chemical female cam lock fitting onto male tote fitting. 13. With PPE still on, open tote valve and check for leaks. Open any other chemical supply valves between tote and chemical tote.

TOTE RECEIVING AND EXCHANGE SOP 14. Turn on pump(s) and bleed the chemical lines of air at chemical pump or before Griffco back pressure valve. 15. Wash down tote area and chemical lines. 16. Wash Down, remove and store acid suit, face shield, etc.

CHEMICAL FEED LINE REPAIR SOP 1.Don appropriate PPE 2.On entering chemical room review all lines for leaks. 3.Use Lock-out/ Tag-out. Turn off power and unplug the chemical pump to be repaired or to pump supplying line to be repaired. If leak is a spray, pump can be turned off through the WebMaster.

CHEMICAL FEED LINE REPAIR SOP 4.Turn off or close valve on bottom of tote and any other valves in the line supplying the pump or line to be repaired. 5.Wash down area of leak. 6.Locate repair supplies 7.Repair or replace chemical tubing, tubing fittings, chemical pump fittings, or chemical pump.

CHEMICAL FEED LINE REPAIR SOP 8. Open bottom tote valve and any valves in the chemical supply line to the pump. 9. Turn on the power to the pump and put the pump into “Hand” or plug pump into a powered outlet. 10. Bleed air out of chemical feed lines at chemical pump or before Griffco back pressure valve.

CHEMICAL FEED LINE REPAIR SOP 11. Check for leaks. If leaking repeat from #3 above. 12. If repair is complete, thoroughly wash down all areas affected by the leak including the chemical pump, the chemical line and fittings. 13. Wash down any affected PPE 14. Remove and store acid suit, face shield, etc.
