Trend analysis for Power Engineering & Mfg Ltd
Between 2018 and 2024, Power Engineering & Mfg Ltd's Total Case Rate improved from 11.7 to 7.6 recordable injuries per 100 full-time workers, a 35% decrease across 6 years of OSHA reporting.
The safest year on record was 2023, at a TCR of 2.8, while 2019 saw the highest rate, at 26.4, a spread of 23.6 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.
Summed across those 6 reporting years, Power Engineering & Mfg Ltd recorded 40 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 6-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)
What is the DART rate formula?
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
3 DART incidents × 200,000 ÷ 132,080 hours worked = 4.54 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

What this grade means for you
Use this grade as a relative read on Power Engineering & Mfg Ltd's reported OSHA injury record versus its Speed changers (i.e., power transmission equipment) manufacturing peers, not a verdict on whether any single site is safe today.
- At 372% of the Speed changers (i.e., power transmission equipment) manufacturing benchmark, Power Engineering & Mfg Ltd reports more injuries than typical peers, ask specifically how the employer is reducing them. Know your rights
- Judge this record against the wider Speed changers (i.e., power transmission equipment) manufacturing sector, where injury rates vary widely, before comparing it in isolation. See the industry
- Grades reflect 2016–2024 filings; check the latest establishment record straight from OSHA, or look up a different employer. Look up another
Safety grades reflect employers' self-reported OSHA Form 300A filings from 2016 to 2024 and can lag current conditions. A grade is not a guarantee that any specific workplace is safe or unsafe today. See our methodology and disclaimer.
