Description: |
|
The report provides statistical
information on occupational injuries in British Columbia for the years
1997 - 2005. Injuries are categorized by type of accident that led
to the injury and the occupation of the injured person. A series of
statistics are provided: counts of injuries, injury rates, claim durations,
average ages, and a distribution by gender. |

Title: |

Trends in injury rates, 1990-1997 |
| |
Order #: |
|
SS035 |
| |
Description: |
|
Injury rates for 16 large
subclasses over the 1990-1997 period were broken down into ergonomic
and traumatic components and were correlated with four potentially
explanatory factors. Some statistical relationships were found between
injury rates and these factors, but the relationships were not large
and were difficult to interpret. |

SS027 |
| |
Description: |
|
Claim duration increased
between 1990 and 1992. Duration is known to depend on a range of factors
including type of injury, age, and gender. Changes in these factors
accounted for a part of the change in duration between 1990 and 1992,
but left most of the increase unaccounted for. |

Data from the 1971 census

workers had different kinds of accidents than did more experienced
workers. |

A proposal is made that
individual injury rates, calculated over employment periods, could
be used where the unavailability of exposure data makes the calculation

turnover has to be allowed for. |

to the injury experience of fallers paid on a piecework basis. Individual
accident rates are used. The analysis adjusted for age, size of firm,
and geographic region. The conclusion was that there was no differnce
in accident rate but there was a difference in injury severity. |

1,051 survey returns
from injured workers were analysed. The survey form showed pictures
of 16 WCB safety posters, and asked the injured workers in each case
whether they had seen the poster. An analysis was done of whether
the types of injuries the workers had were less likely to be the injury
types that were the subject of the posters they had seen. No significant
correlations were found. |
