The Washington State Legislature rules apply to WAC 296-155-375, as cited in Washington State Legislature. The UpCodes rules apply to Jacks-Lever and Ratchet, Screw, and Hydraulic, as cited in UpCodes. The Legal Information Institute rules apply to 29 CFR § 1926.305, as cited in Legal Information Institute.
Note that the Washington State Legislature also requires specially designed jacks constructed for specific purposes to meet the approval of the department of labor and industries before being placed in service, as cited in Washington State Legislature. This design approval requirement is distinct from the control part design hazard rule listed in the table. Together, the table topics and this approval item are the ten checks.
Keep the claim tied to each named source. Do not treat one publisher's rule as every firm's rule, and do not treat one jurisdiction's rule as the rule everywhere. Verify which jurisdiction's regulations apply to your specific job site before relying on a single row.

When to inspect: service conditions and shock loads
Inspection timing for hydraulic jacks depends upon the service conditions and on how the equipment is used. The Washington State Legislature states that you must thoroughly inspect each jack at times which depend upon the service conditions Washington State Legislature. This means the frequency of your checks must reflect the actual operating environment and stress levels the jack experiences on your site. The Legal Information Institute provides a parallel requirement, noting that each jack shall be thoroughly inspected at times which depend upon the service conditions Legal Information Institute. Because both sources tie the inspection schedule to service conditions, your daily log should record the specific conditions present during the shift, such as load weight or vibration levels, to justify the timing of your checks.
A critical trigger for immediate inspection occurs when a jack is subjected to an abnormal load or shock. UpCodes specifies that for a jack subjected to abnormal load or shock, inspection must happen immediately before and immediately thereafter UpCodes. The Legal Information Institute reinforces this timing, stating that for a jack subjected to abnormal load or shock, inspection is required immediately before and immediately thereafter Legal Information Institute. Writing both inspections in the daily record is recommended documentation of the check performed right before an expected abnormal load and the check performed right after it. If a jack experiences a sudden impact or a load significantly different from its normal operating range, you cannot rely on a routine morning check. If an abnormal load is planned, inspect immediately before it and immediately thereafter. If a shock has already occurred, inspect immediately thereafter.
Maintenance actions: lubrication and parts
Routine maintenance for hydraulic jacks includes lubrication and part inspection. These steps are distinct from the initial setup checks and can be logged separately in your daily record.
Lubrication intervals Your site log can track when each jack receives its lubrication. The rule is straightforward: all jacks shall be properly lubricated at regular intervals, according to UpCodes. In your daily log, record the date and time of lubrication for each unit. If a jack has not been lubricated within the interval you have established for your site, flag it for immediate servicing before it is used for lifting. The log entry should confirm that the lubrication was performed and note the type of lubricant used, as this helps verify compliance with the "regular intervals" standard.
Part defect checks You must examine any repair or replacement parts for possible defects, according to Washington State Legislature. This check is critical because a single defective component can compromise the entire lifting operation. The same requirement is stated in federal regulations: repair or replacement parts shall be examined for possible defects, according to Legal Information Institute. When logging this step, specify which parts were inspected. For example, if you replaced a hydraulic seal or a ram extension, note the part number and the condition of the surrounding components. Do not assume that a new part is defect-free; the inspection must verify that the part fits correctly and shows no signs of damage or wear. If a part fails this check, the jack must be removed from service and tagged out of order, as detailed in the out-of-order protocols section.
Safety setups: blocking, cribbing, and slippage prevention
Physical stability is a core part of the daily jack inspection. You must verify that the jack is resting on a solid surface before the crew begins lifting operations. See Log lifting sling inspections: 6 checks before the lift when the lift also uses slings. When it is necessary to provide a firm foundation, you must block or crib the base of the jack, according to Washington State Legislature. This requirement applies specifically when the ground or surface is not naturally firm enough to support the load without additional support.
Check the base of each jack for proper blocking or cribbing. If the foundation is unstable, add the necessary blocks or cribs to create a firm base. The rule is clear: when a firm foundation is needed, you must block or crib the base, as stated by the Washington State Legislature. Do not assume the ground is stable; verify it with your eyes and hands.
Slippage at the top of the jack is another critical hazard. Where there is a possibility of slippage of the metal cap of the jack, you must place a wood block between the cap and the load, according to Washington State Legislature. This prevents the metal cap from sliding off the load during the lift.
Inspect the contact point between the jack cap and the load. If the metal cap could slip, place a wood block between them. The Washington State Legislature requires this wood block whenever slippage is possible. This is a simple but vital safety measure.
Record these checks in your daily log. Note whether blocking or cribbing was used at the base. Note whether a wood block was placed between the cap and the load. These entries prove that you followed the safety setup rules.
The Washington State Legislature provides these specific rules for jack safety. Follow them exactly. Do not guess. Do not skip. The physical setup is as important as the mechanical checks.
Out-of-order protocols and design hazard control
When a hydraulic jack fails inspection, immediate tagging is required to prevent accidental use. Under WAC 296-155-375, you must tag jacks which are out of order accordingly, and you must not use them until repairs are made, according to Washington State Legislature. This specific requirement for tagging and suspension of use is also codified in the federal regulations found at 29 CFR § 1926.305, which states that jacks which are out of order shall be tagged accordingly, and shall not be used until repairs are made, according to Legal Information Institute. UpCodes reinforces this protocol by noting that jacks which are out of order shall be tagged accordingly, and shall not be used until repairs are made, according to UpCodes. These three sources align on the necessity of a visible tag and a strict ban on operation until the defect is resolved.
Design standards also dictate how jacks are built to protect operators. WAC 296-155-375 specifies that control parts must be so designed that the operator will not be subjected to hazard, according to Washington State Legislature. This design mandate ensures that the physical interface between the worker and the machine does not create new risks during operation. The same regulation requires that specially designed jacks constructed for specific purposes must meet the approval of the department of labor and industries before being placed in service, according to Washington State Legislature.

Illustrative example of one shift
One jack stays on a steady lift for one shift, so the log shows one thorough inspection tied to those service conditions. The crew then plans one abnormal load. The log shows one inspection immediately before that load and one inspection immediately thereafter. The base needs a firm foundation, so the crew blocks the base. Slippage of the metal cap is possible, so a wood block goes between the cap and the load. Lubrication is marked done. No repair part is fitted. The jack stays in order, so no tag is applied. It is not exposed to freezing temperatures. Control parts are noted so the operator will not be subjected to hazard. The jack is not specially designed for a specific purpose.
Sample line for the daily jack inspection log
Use this sample line to record selected checklist items on your site log. Record the details for each jack you verify before the crew starts work. The table below provides the structure for your daily entry.
| Check Item | Publisher Source | Date | Inspector | Status/Notes |
|---|---|---|---|---|
| Example | Control part design and service check noted | Shift day written in words | Crew member on duty | Entry marked clear |
Record the specific date and the name of the inspector who performed each check. Note any defects found during the part examination or any changes in service conditions that trigger an inspection. If a jack is tagged out of order, record the tag number and the reason for removal. For jacks subjected to shock loads, document the inspection performed immediately before and after the event. Verify that antifreeze liquid is present in hydraulic jacks exposed to freezing temperatures. Confirm that specially designed jacks have the required department approval on file. This sample helps you keep recommended documentation fields for the daily site record, including control part design and specially designed jack approval.
Today, review your current jack inspection log and add a field for the abnormal load check so the before and after inspections can be written down.
FAQ: how to inspect and log hydraulic jacks for the daily site record
When must a jack be inspected after an abnormal load?
