Confined Space Innovations meet and exceed the OSHA 29CFR 1910.146 standards for Permit Required Confined Spaces.


Regulations &


OSHA 1910.146   defines "confined space" as a space that

  • Is large enough and so configure that an employee can bodily enter and perform assigned work.

  • Has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults and pits are spaces that may have limited means of entry.); and

  • Is not designed for continuous employee occupancy.

OSHA 1910.146(c)(2)   Signage

  • If the workplace contains permit spaces, the employer shall inform exposed employees, by posting danger signs or by any other equally effective means, of the existence and location of and the danger posed by the permit spaces.

OSHA 1910.146(c)(3) Entry Barrier

  • If the employer decides that its employees will not enter spaces, the employer shall take effective measures to prevent its emplyees from entering the permit spaces.

Even if properly trained, workers may forget their training and/or disregard proper entry procedures and enter a confined space without PPE because they are overcome by the natural emotion to rescue a coworker. Although companies are required to and do have written procedures and programs related to confined space entry, it does not release the company from liability due to an employees disregard of those procedures, no matter if the employee is regular, temporary or contract. As far as OSHA is concerned, employers are responsible for the safety of ALL workers.

Repairs & maintenance and cleaning & inspections account for almost one-quarter of confined space related fatalities.

From 1992-2005 there were 431 confined space incidents with 530 fatalities in the United States due to oxygen deficient and/or toxic atmospheres.


08/18/2009 - 12/31/2009: 36 workers died and 6 were hospitalized while conducting confined space entries.


2010: There were 63 fatalities and 28 hospitalizations involving confined spaces.


01/01/2011-08/01/2011: There were 22 fatalities and 3 hospitalizations related to confined spaces.

During a study done in 2006 by a California company, it was found that approximately one-fifth of the confined space incidents result in multiple fatalities. Data also indicated that for every fatality due to oxygen-deficient and/or toxic atmosphere, 2 non-fatal injuries occur, one of which requires hospitalization. More often than not, those additional injuries are to rescuers.
