Inspect supplied protective record-review dates and intervals; no laboratory procedures or compliance judgment.

Description

Return record/review ages and remaining review margin.

Laboratory-safety administration tracks inspection records, equipment counts, training coverage and supplied policy limits. A local balance or current-status flag can reveal a record gap while actual equipment condition, training competence and adequate protection require independent verification.

Return record/review ages and remaining review margin.

When to use this tool

Use Protective Record Review Gap when checking the stated laboratory-safety record, timing, capacity or inventory convention.

How to use the tool and how it works

  1. Enter recordCreatedDate, lastReviewDate, evaluationDate, suppliedReviewDays. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read recordAgeDays, reviewAgeDays, reviewMarginDays. Use the output convention below.

Return record/review ages and remaining review margin. Validate real date-only strings with created <= review <= evaluation and nonnegative whole suppliedReviewDays; compute UTC day ages and reviewMarginDays = interval-reviewAge.1

Limitations and assumptions

  • Modern date years 0000-9999 are accepted; actual inspection, current safety status and appropriate review frequency are not verified.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Inspect actual equipment and verified records under the applicable procedures; use qualified risk assessment and professional judgment to determine adequate protection and actual authorization.
