How to write a silica exposure control plan that holds up on the jobsite
Since OSHA's construction silica standard took effect, the written exposure control plan has become one of the documents GCs, owners, and compliance officers ask for first. Many of those plans are generic: a copy of the standard plus a paragraph promising to "use Table 1." That doesn't meet the rule, and it doesn't help the foreman who has to decide whether the anchor crew needs respirators today. The free template above builds the plan from your actual tasks and ties each one to its Table 1 row, required controls, and required respirator.
The four required elements of the written plan
29 CFR 1926.1153(g)(1) says the plan must contain at least:
- The tasks that involve exposure to respirable crystalline silica. Be specific: "drill anchors for hangers overhead in concrete deck," not "drilling."
- The engineering controls, work practices, and respiratory protection used for each task. For Table 1 tasks, that means the Table 1 controls and respirator. For everything else, it means whatever your exposure assessment says is needed.
- The housekeeping measures used to limit exposure.
- The procedures used to restrict access to work areas when necessary, to minimize how many employees are exposed and how much, including exposures generated by other employers or sole proprietors.
Beyond the four elements, the employer must review and evaluate the plan's effectiveness at least annually (g)(2), make it available to employees and their representatives on request (g)(3), and designate a competent person to make frequent and regular inspections of job sites, materials, and equipment (g)(4). The template's plan tab has a section for each of these.
Section 1: tasks, Table 1 rows, and respirators
Table 1 in 1926.1153(c) is the reason most contractors can comply without air sampling. If you fully and properly implement the listed controls for a task, you don't have to assess exposure for that task. The table has 18 equipment and task rows, and several split by condition. A handheld power saw outdoors has different respirator requirements than the same saw indoors. The template's Table 1 Reference tab lists each row and condition separately so the dropdown picks exactly one.
For each task row you enter:
| Column | What to enter |
|---|---|
| Task / Activity | What the crew is doing, where, and to what. |
| Material | Concrete, CMU, brick, stone, mortar, fiber-cement, terrazzo, tile. |
| Table 1 row | Pick from the dropdown, for example "(vii) Handheld / stand-mounted drill incl. rotary hammer." |
| Hrs / shift | The employee's combined time on all Table 1 tasks in the shift. |
| Required controls | Fills in from the Table 1 row: water feed, shroud and dust collector airflow, filter efficiency, HEPA vac. |
| Required respirator | Switches between the ≤4 hr and >4 hr value, showing None, APF 10, or APF 25. |
The 4-hour rule most plans get wrong
Under 1926.1153(c)(3), when an employee does more than one Table 1 task in a shift and the total time goes over four hours, the more-than-4-hours respirator applies to every task. An electrician who cores for 2 hours and chips for 3 hours is over four hours on both. That's why the hours column asks for combined time.
Conditions that come with Table 1
Implementing Table 1 also means: exhaust as needed for indoor or enclosed work so visible dust doesn't build up; enough water flow on wet methods to minimize visible dust; and for enclosed cabs or booths, keeping them clean with working door seals and gaskets, positive pressure from filtered fresh air, and heat and air conditioning. The competent person inspection checks each of these.
When a task isn't on Table 1
If the task isn't listed, or you can't fully implement the listed controls (no water on a frozen day, a dust collector without enough airflow), you are under paragraph (d). You have to assess exposure by air monitoring or objective data, keep exposures at or below the permissible exposure limit of 50 µg/m³ as an 8-hour TWA, and choose respirators from the results. The dropdown's last option marks those tasks so they stand out in the plan.
Sections 2 and 3: housekeeping and restricted access
Housekeeping under 1926.1153(f) comes down to two prohibitions: no dry sweeping or dry brushing where it could contribute to exposure unless wet sweeping, HEPA vacuuming, or another low-dust method isn't feasible; and no compressed air to clean clothing or surfaces unless it is used with a ventilation system that captures the dust cloud or no alternative is feasible. The template pre-loads those plus the field practices that make them work: picking up slurry before it dries, bagging collector waste, and changing vac filters outdoors.
Restricting access is the element plans most often leave out, and it explicitly covers other employers' dust. The template includes barricades and signage, scheduling dusty work away from other trades, positioning work downwind, coordinating at the foreman meeting, and sealing indoor areas with exhaust.
The medical surveillance tracker
Paragraph (h) requires medical surveillance, at no cost to the employee, for everyone who will be required by the standard to wear a respirator 30 or more days per year. The tracker handles the dates:
- Surveillance: set to Required when respirator use is 30+ days a year (Yes, or estimated days of 30 or more).
- Baseline exam due: initial assignment + 30 days. If the employee had a qualifying exam within the last three years, enter that date as the baseline.
- Next exam due: the latest exam + 3 years, using EDATE with 36 months. Periodic exams repeat the baseline except the latent TB test, and the PLHCP can call for them more often.
- Status: OVERDUE in red, Due within 60 days in amber, Current in green.
- Written opinion due: exam + 30 days. It flags red if the opinion hasn't come back.
Keep medical results confidential. The employer's written opinion from the PLHCP contains only the exam date, a statement that the exam met the standard, and any respirator limitations (plus exposure limits or specialist referral only if the employee authorizes it in writing). The tracker stores dates and limitations, not diagnoses.
The competent person inspection
The standard defines the competent person as someone who can identify existing and foreseeable silica hazards and has authority to take prompt corrective action. The inspection tab gives them a structured walk:
- Engineering controls: water on and flowing, shrouds attached, collector airflow and 99% filter, filter-cleaning mechanism, indoor exhaust, cab condition.
- Work practices: tools used per the manufacturer, task matches its Table 1 row, combined hours tracked.
- Respiratory protection: required respirators worn, fit tests current, clean-shaven at the seal.
- Housekeeping: no dry sweeping, no compressed air, slurry controlled.
- Access and other employers: area barricaded, no exposure to or from other trades.
- Plan and training: plan on site and current, and the crew can name the competent person and the controls.
% Compliant = Yes ÷ (Yes + No). Every "No" gets a corrective action, a responsible person, and a due date. If Table 1 controls can't be fully implemented, stop the task. It needs an exposure assessment, not a workaround.
Common silica plan mistakes
- A generic plan with no project-specific tasks.
- Using the ≤4-hour respirator column for a worker whose combined tasks exceed four hours.
- Shop vacs sold as "HEPA" that don't meet the airflow or filter spec for the tool.
- No provision for dust from other employers.
- Medical surveillance tracked on memory instead of dates.
- A competent person named on paper who never inspects.
