Chemical / SDS / Silica
A masonry crew plans to dry-cut concrete block with a handheld power saw for most of the shift because the foreman says, “The saw SDS only says wear a dust mask.” The job is US construction. You are the CSP: which silica compliance path governs the cut, and what changes if the exact Table 1 controls are not fully implemented?
Updated . Independent CSP-11 practice. Not BCSP-endorsed. No pass guarantee.
Decision rule
SDS is a starting file, not the control. Silica needs Table 1 or an exposure assessment.
A binder of SDSs does not wet-cut.
In 20 seconds
- SDS is a starting file, not the control.
- Silica needs Table 1 or an exposure assessment.
- Separate hazard communication from substance-specific silica duties.
- Read the 50 µg/m³ PEL and 25 µg/m³ action level as eight-hour TWA values.
How to apply Chemical / SDS / Silica
THEORY: Chemical identity, routes, controls on the SDS. Silica construction: specified exposure control methods or measured exposure. CALC: None unless a stem gives % silica. FIELD: Dry cutting block with only an SDS on the truck. Wet method or shrouded tool. ASSESS: ‘We have SDSs’ as silica control is the trap.
Worked case
Wrong first move: Hand out SDS. Correct move: Apply the specified method or assess exposure.
Why the rule holds
Related: 56, 61.
Same rule, different setting
A foreman dry-cuts refractory in a heater because “the SDS says wear a dust mask,” and wet methods would slow the outage. You are the CSP. The question is what GHS/SDS actually does versus what a silica rule requires.
On a busy jobsite, chemical sds silica shows up when schedule pressure sells a permit, rotation, or PPE package while design still can change. SDS/GHS is hazard communication (16 sections): identity, hazards, controls as information — not a substitute for hierarchy or for a substance-specific standard. Discriminate the open row before you laminate another card.
Picture / model
Route construction silica work to the correct paragraph: Table 1 specified controls in 1926.1153(c); alternative exposure control, PEL and assessment in (d); housekeeping in (f); and written-plan/competent-person duties in (g). An SDS dust-mask note does not replace these controls.
Exam traps
Original SafePath contrasts for Chemical / SDS / Silica. These are study traps, not recalled BCSP items.
| Trap | Correct read |
|---|---|
| SDS / GHS | Communication — 16 sections; not the exposure plan by itself |
| Table 1 / specified control | Engineering/work-practice recipe that can stand in for monitoring when fully followed |
| Silica PEL 50 μg/m³ | OSHA legal 8-hour TWA (AL 25 μg/m³) |
| TLV / REL | Advisory — PELTLV if used as the citation limit |
| Disposable “dust mask” | PPE — last, and often the wrong APF for dry RCS |
Field move
Dry cutting because a sheet mentions a dust mask skips the water delivery the stem says the table row specifies.
Scenarios
Scenario 1 · Fundamental · CSP-11 D6.01
A foreman dry-cuts concrete masonry units because a saw manufacturer's SDS mentions a dust mask. The applicable OSHA construction silica Table 1 row specifies water delivery. What is the decision?
Best action: Use the listed water-delivery control as specified or follow the standard's alternative exposure-assessment and control route; an SDS mask note is not Table 1 compliance.
Why: Evaluate the best response. The foreman dry-cuts concrete masonry because a saw sheet mentions a dust mask, and the applicable construction silica row in the stem specifies water delivery. Use that water delivery as specified, or follow the standard's alternative exposure-assessment and control rou…
Scenario 2 · Applied Scenario · CSP-11 D6.01
Under the applicable federal OSHA construction silica standard, which paired eight-hour time-weighted average values are the PEL and action level?
Best action: PEL 50 μg/m³ and action level 25 μg/m³.
Why: Evaluate the best response. The federal construction silica pair stated by this item is a PEL of 50 micrograms per cubic meter and an action level of 25 micrograms per cubic meter, both as eight-hour averages. This item does not reconstruct the rest of the silica standard. PEL 50 mg/m³ and action l…
Scenario 3 · Applied Scenario · CSP-11 D6.01
A report relabels 50 μg/m³ of respirable crystalline silica as 50 mg/m³. What is the numerical error?
Best action: A factor of 1,000; 50 μg/m³ equals 0.050 mg/m³.
Why: One milligram is 1,000 micrograms, so 50 μg/m³ = 50/1,000 = 0.050 mg/m³. Writing 50 mg/m³ overstates the concentration by 1,000. The 24.45 gas factor and the eight-hour averaging time are not this unit conversion. OSHA's respirable crystalline silica PEL is expressed as 50 μg/m³, which makes the pr…
If the stem says this
| Stem signal | Best direction |
|---|---|
| recognize the task | Identify material, equipment, cutting method, duration, location and other exposed workers. |
| check table 1 | Find the exact construction task and fully implement specified controls; respirator requirements can depend on duration and indoor/outdoor conditions. |
| assess if needed | When Table 1 is not fully and properly implemented, use the rule's performance or scheduled monitoring options and compare eight-hour exposure correctly. |
| control and verify | Use water delivery, shrouds and HEPA capture as specified; maintain equipment, train and inspect during actual cutting. |
Check before you leave
- ✓ Separate hazard communication from substance-specific silica duties.
- ✓ Read the 50 µg/m³ PEL and 25 µg/m³ action level as eight-hour TWA values.
- ✓ Use Table 1 only for a task and controls that fully match its specifications.
- ✓ Choose wet methods, shrouds or HEPA controls before relying on a generic mask.
- ✓ Use Table 1 only when its task and controls fit fully.
- ✓ Both the action level and PEL use an eight-hour TWA basis.

Chemical / SDS / Silica study questions
- What decision does the Chemical / SDS / Silica class train?
- SDS is a starting file, not the control. Silica needs Table 1 or an exposure assessment. This is independent SafePath CSP practice for CSP-11 D6.01. It is not an official BCSP item and it is not a pass guarantee.
- What exam trap shows up in Chemical / SDS / Silica?
- A common miss treats this as sufficient: SDS / GHS The stronger read is: Communication — 16 sections; not the exposure plan by itself
- How does Chemical / SDS / Silica map to the CSP-11 blueprint?
- SafePath maps this class to CSP-11 D6.01 in Domain 6, Occupational Health and Applied Science (10% of the published blueprint). Use the public outline for study planning. SafePath is not affiliated with or endorsed by BCSP.
