General
Name the five elements of 5S
Sort, Set in order, Shine, Standardize and Sustain,
One waste-management option uses an item again with little or no processing, while the other breaks it down and reprocesses the material into something new.
What is the difference between reuse and recycling?
This term refers to an unplanned release of a hazardous substance that poses a significant risk
What is a chemical spill
In the hierarchy of controls, PPE is considered this because it doesn’t remove the hazard and relies on correct human use every time.
What is the last line of defense / least effective control?
What is the main reason to keep solvent containers tightly closed?
To reduce evaporation and vapor exposure
What does the acronym LTIFR stands for?
Lost Time Injury Frequency Rate
The document that tells you environmental hazards and spill cleanup guidance for a chemical.
What is the SDS (Safety Data Sheet)?
Can N95 particulate respirator protect against solvent vapor? Why?
No- A particulate filter does not remove solvent vapor .Respiratory protection must be selected for the contaminate and exposure condition
This common personal factor can break the seal of tight-fitting respirators and is a frequent reason for failed fit tests.
What is facial hair/stubble in the sealing area?
A substance that dissolves a solute to form a solution
What is a solvent?
What is the difference between a hazard and a risk?
Hazard = potential source of harm; Risk = likelihood × severity of harm given exposure/controls.
This engineering control is designed to capture leaks from tanks/drums so the release doesn’t reach soil or drains.
What is secondary containment (bunding/diking)? /
Prevent access to moving parts and contain ejected parts
What is machine guard is mainly intended to:
Limited protection against light liquid splashes (limited spray)chemical protective clothing - Which Type
What is meant “Type 6 ” protection in chemical protective clothing
This GHS pictogram (skull and crossbones) indicates chemicals that can cause serious harm or death from short exposure by inhalation, ingestion, or skin contact.
What is acute toxicity?
What principle gives workers the authority to halt operations if they believe conditions are unsafe?
Stop Work Authority (SWA)
Hierarchy of Waste Management (most preferred → least preferred)
What type of device can be put on a machine to ensure machine operation if a guard is opened or removed
What is an Interlock
These respirators cannot be used in oxygen-deficient atmospheres because they do not supply oxygen.
What are air-purifying respirators (APR)?
The SDS section that lists incompatibilities, conditions to avoid, and hazardous decomposition products is this one.
What is Section 10: Stability and Reactivity?
What are Included in SLSR
1.Work at Height 2.Working on Powered System 3. Line Break 4. Confined Space 5. Work At Explosive Atmosphere 6.Lifting 7. Excavation 8. Traffic
“Solvent use” is an example of this, while “VOC emissions” is the resulting consequence.
What is an environmental aspect (vs. impact)?
What is the difftence between inherent risk and resodual risk
inherent risk is assessed before controls and resodual risk is what remians after controls are applied ,
This is the term for a chemical passing through an intact glove material at the molecular level, even when there are no visible holes.
What is permeation?
This type of occupational exposure limit is a 15-minute time-weighted average designed to prevent acute effects from short spikes in exposure.
What is a Short-Term Exposure Limit (STEL)?
