INDUSTRIAL HYGIENISTS SHOULD ADDRESS THE

RESPIRATORY HAZARDS OF NANOPARTICLES

– aka UFP – IN THE WORKPLACE

Nanoparticles may seem new but UFP (<100 nm ultrafine particles) studies go back decades in outdoor air pollution research.

Engineered nanomaterials are used in consumer products, such as cosmetics, sunscreen and related personal care products such as toothbrushes.2

Industrial use of nanomaterials occurs in the manufacture of

electronics, automotive and aerospace products.2

Additive manufacturing uses 3D printers and lasers to heat/melt

/sinter powders of metal, polymer, biological nanoparticles.

Well understood source of combustion-derived nanoscale UFP is welding, for which fume extractors are effective.

WHERE EXPOSURE TO UFP OCCURS

HOW NANOSCALE UFP CAN DAMAGE THE BODY

Heart: Acute myocardial

infarction, atherosclerosis5

Lungs: Particle-induced

inflammation3

DNA: Changes in

generic code regulation6

Brain: Cognitive decline4

HEPA filters capture particles via diffusion, interception, inertia, van der Waals forces, plus the interplay of:

PROTECTION FROM PARTICLES STARTS WITH H, AS IN H E P A

Particles of 0.3 microns are noted when HEPA filtration efficiency is discussed, creating the false impression that HEPA does not capture smaller particles. Research has shown HEPA filtration is 99.97% efficient at capturing 0.3 micron particles, the most difficult size for HEPA technology.1

Particles of lesser and

greater size are captured even more efficiently.

NIOSH: HEPA EFFECTIVE TOOL FOR NANOPARTICLE CAPTURE

“HEPA filtration has been shown to be effective in capturing nanoscale particles and should be considered in situations where emissions may be regular, where processes are repeated, and where higher quantities are used in a way that may lead to emissions.”

Nanoscale particles are a health hazard.

Solutions exist in existing air fi ltration technology.
