Metalworking Fluids


Goals

Unsafe fluids and health effects Controlling worker exposure Quiz


Types of Metalworking Fluids

Straight oil Soluble oil Semisynthetic Synthetic


Signs of Unsafe Fluid

Low sump level Abnormal fluid appearance Foul smell Floating matter Tramp oil


Signs of Unsafe Fluid

Excessive foam Dirty machines

or trenches Employees with

skin irritation Employees with respiratory irritation Other fluid-related problems


Labels and MSDSs

Identity of chemical and manufacturer

Hazard warnings Physical characteristics Health effects Safe handling procedures Emergency response


Health Effects—Skin

Contact dermatitis Irritant dermatitis Allergic dermatitis Causes of dermatitis Acne


Health Effects—Respiratory

Irritation of the lungs, throat, and nose

Symptoms Asthma Chronic bronchitis Hypersensitivity

pneumonitis Other factors


Goals



Control Misting

Use low-pressure flow Use mist suppressants Interrupt or reduce flow when practical Fix leaks Avoid compressed air to dry parts


Isolation

Mechanical parts handling

Machine enclosures Splash guarding Isolation booths


Exhaust Ventilation

Local exhaust ventilation Enclosure exhaust hood Exterior exhaust hood General ventilation


Exhaust Hoods

Close capture enclosure Total or complete enclosure Tunnel enclosure Push-pull ventilation Side-draft hood Canopy hood Downdraft hood


Inspection and Maintenance

Fluid filtration systems

Fluid delivery systems

Ventilation systems Fluid chemistry Enclosures and splash guards


Safe Use Procedures

Minimize exposure to fluids Recognize unsafe fluids Know how to add fluids to a machine Recognize if ventilation not working Know how to get something fixed


Fluid Management Program

Person responsible for fluid systems Person designated for adding materials Fluid testing procedures Tracking data Employee participation Training program


Control Fungi Growth

Clean system before adding new fluid

Maintain fluid at proper concentration

Quality make up water

Control Fungi Growth (cont.)

Add biocides Remove metal chips

and fines Remove tramp oil Practice good

housekeeping



Fluid Change

Add cleaner with biocide Remove old fluid Remove chips and swarf Circulate cleaning solution Change filters Refill with fresh fluid


Housekeeping

Clean floors, equipment, and work area

Wear protective clothing Clean up spills

immediately Properly dispose of waste

and contaminated items


Personal Hygiene

Clean skin with soap and water

Minimize contact with fluids

Change contaminated clothing

No food, drink, or tobacco near fluids Use barrier and moisturizer creams


PPE

Hazard assessment Chemical resistant gloves Protective clothing Eye protection—glasses,

goggles, face shields Foot protection


Respirators

Engineering or administrative controls

5 mg/m3 for mineral oil mist

Written respiratory program N-, R-, or P-series

filtering facepiece Recommended respiratory protection


Exposure Assessment

Qualitative assessment Personal air sampling Area air sampling Source air sampling


Medical Monitoring

Early identification of disease

Periodic review of employee’s health

Employee evaluation Symptoms to monitor Self-report medical

symptoms


Goals



Summary

Know the signs of unsafe metalworking fluids Report symptoms of skin or respiratory

health effects Follow personal hygiene practices Wear PPE Monitor and control fungal growth
